Every four years, scores of American people flood churches, schools, homes, and auditoriums to cast their ballots for the future of American leadership. But amid the highs and lows of election night, there is an ongoing conversation about how the votes are being counted.

As results slowly roll in, voters struggle with long lines and faulty machinery in key battleground states, prompting debates on the efficiency of the U.S. voting process. In an age where American Idol results can be instantaneously transmitted over a mobile device, why are we still feeding paper ballots into machines that look like props from ‘90s movies?

On the one hand, countries like Canada, Norway and Australia have already experienced success with their adoption of online voting systems, and proponents say going digital will boost voter turnout and Election Day efficiency. On the other, naysayers cite hacking, malware, and other security threats as deal-breakers that could threaten the backbone of American democracy.

So what are the facts behind this debate? Below, we’ve outlined key arguments for and against online, email, and electronic voting systems, to help users at home move beyond the pre-election campaign hype.

Electronic voting: Better or worse than paper ballots?

Since there have been elections, there have been people tampering with votes. Given this, experts are justifiably concerned with any technology that could introduce new points of access to the data stored during an election. Nevertheless, a handful of states now use electronic voting machines exclusively—Delaware, Georgia, Louisiana, New Jersey and South Carolina—and even notorious battleground states Ohio and Florida have made the move toward paperless votes.

The concern is that when there is no physical ballot, it becomes next to impossible to determine if there has been tampering—especially in the case of a close election. The contested 2000 Bush-Gore race comes to mind as an example of the stark importance of reliable election machinery. In 2012, Pennsylvania voting machines were taken out of service after being captured on video changing votes from one candidate to another.

Still, most of these machines now supply a paper trail to guard against tampering, and a vast majority undergo frequent, mandatory testing. The machines are also not connected to the Internet and are segregated from any network-connected devices. In terms of physical security, the machines themselves are secured with locks and tamper-evident seals, and they’re heavily protected when transported to and from polling places.

Hacking the vote: It’s easier than you think

While electronic voting promises efficiency and convenience, the reality is that these systems face significant vulnerabilities that make them easy targets for hacking.

Attackers don’t need to hack every voting machine individually. They only need to target the broader voting ecosystem through several key attack vectors. For one, supply chain risks represent one of the most concerning threats, where malicious components or software can be introduced during manufacturing or updates. Misconfigured systems and outdated firmware create entry points that cybercriminals actively seek out, while exposed network ports can provide side-channel access to supposedly isolated voting infrastructure.

Beyond direct machine tampering, sophisticated attacks focus on ballot definition files—the digital templates that determine how votes are recorded and counted. Manipulating these files can alter election outcomes without voters realizing it. Similarly, result reporting systems that transmit vote tallies from polling locations to central counting facilities present attractive targets for those seeking to disrupt electoral processes.

Recent security research demonstrates these vulnerabilities aren’t theoretical. In 2003, cybersecurity researchers at Johns Hopkins University documented significant security gaps in widely used electronic voting systems during controlled testing environments, revealing that basic network intrusion techniques could compromise vote tallies without detection. Meanwhile, a 2022 audit conducted by election security experts in Georgia identified configuration errors in electronic polling systems that could have allowed unauthorized access to voter data and ballot information.

Perhaps more concerning is how disinformation campaigns around unofficial election results can amplify doubts about electoral integrity, regardless of actual system security. These campaigns often spread false information about electronic voting fraud or online voting hack attempts, creating confusion that undermines public trust in legitimate election outcomes.

It’s crucial to understand that the primary impact of these vulnerabilities often isn’t direct vote manipulation—it’s the erosion of voter confidence in our democratic processes. When people doubt that their votes count accurately, it weakens the foundation of democratic participation.

Privacy & security concerns in online voting

Will our presidential elections ever go the way of American Idol? Despite advances in technology, the vast majority of Americans must vote in person or via mail-in ballot. At present, only very limited electronic voting options exist, primarily for specific voter groups and circumstances, such as:

Military and overseas voters: The Uniformed and Overseas Citizens Absentee Voting Act (UOCAVA) allows military personnel and overseas citizens to return marked ballots electronically in some states. However, this typically involves downloading a ballot, marking it, and returning it via secure email or portal—not full online voting.
Voters with disabilities: These accommodations vary by state. Some states offer electronic ballot marking tools or accessible voting systems for voters with disabilities. These systems often allow electronic marking but require printing ballots for submission, maintaining a paper trail for verification.
Citizens displaced by natural disasters: During an election cycle when many New Jersey residents were affected by Hurricane Sandy, officials established email as an alternative voting method. But as Election Day loomed, the system was soon blamed for a slew of issues.

Vulnerabilities in online voting systems

Understanding the vulnerabilities that plague electronic voting systems isn’t about creating fear, but about building stronger defenses. Below, we have listed some of the potential attack vectors to help you make informed decisions about digital democracy.

The email software

In email voting, unencrypted emails pose a serious security risk because they can be easily intercepted, spoofed, or altered in transit. When a ballot is sent without encryption, it travels across networks in plain text, allowing cybercriminals to access and modify its contents before it reaches election officials. Attackers also might impersonate legitimate voters by sending forged emails or inject malware into attachments that appear to be ballots.

The device

Computers used to send or receive the emails can be compromised to change or block a voter’s choices. When you cast your ballot online, malware can intercept your vote before it even leaves your device. In addition, the receiving computer will need to open attachments sent by unknown users to tally the votes, one of the most common causes of malware infections.

Credential theft

Phishing attacks specifically target voting credentials, often through fake election websites or deceptive emails. Multi-factor authentication and government-issued digital certificates provide essential barriers. In 2023, the National Institute of Standards and Technology released its Digital Identity Guidelines that recommended biometric verification combined with secure tokens for high-stakes digital transactions like voting.

Man-in-the-middle attacks

Your vote travels across networks where attackers might intercept or modify it. To thwart these attacks and ensure your ballot remains tamper-proof during transmission, end-to-end encryption with cryptographic signatures can be integrated into online voting systems. Advanced protocols such as homomorphic encryption allow vote counting without exposing individual choices.

Server-side vulnerabilities

Voting servers face constant attack attempts. Independent security audits, isolated network environments, and blockchain-based verification systems can help maintain integrity. Regular penetration testing, as recommended in the Election Assistance Commission’s 2023 Voluntary Voting System Guidelines, identifies weaknesses before they’re exploited.

Distributed denial of service

DDoS attacks can overwhelm voting portals during critical periods. Distributed server architecture, traffic filtering, and backup submission methods could ensure continuous access, while cloud-based solutions provide scalable protection against volume-based attacks.

Ballot secrecy

Online systems must balance verification with privacy. Protocols such as zero-knowledge proof could allow voters to confirm that their ballot was counted without revealing their choices. Anonymous credential systems separate voter identity from vote content.

Auditability challenges

Digital voting requires verifiable paper trails or cryptographic receipts. This can be addressed with voter-verified paper audit trails (VVPAT) and risk-limiting audits that provide the transparency necessary for public confidence.

Cyber threats to voting abound long before Election Day

In this digital age, threats to the voting process start well before election day. Cybercriminals take advantage of the campaign fever when citizens turn to technology for updates on the election process or news about running candidates.

Amid all this, your role as a voter includes staying informed about these protections and choosing secure voting methods when available or legitimate information sources. Democracy thrives when citizens understand both the possibilities and precautions of digital participation.

Fake voter registration websites: Scammers create convincing look-alike sites that mimic official election portals to steal your personal information. These sites often appear in search results with urgent messaging about registration deadlines, but they’re designed to harvest your data for identity theft or voter suppression purposes.
Phishing texts and emails about “polling changes”: You might receive official-looking messages claiming your polling location has changed, voting has been extended, or you need to “confirm” your registration via text or email. These communications often create false urgency to trick you into clicking malicious links or sharing sensitive information.
Impersonation of election officials: Scammers pose as election workers, poll supervisors, or government officials via phone calls, texts, or door-to-door visits. They may claim there are problems with your registration, then request personal information to “verify” your eligibility.
Malinformation hotlines: Fraudulent phone lines spread false information about voting procedures, dates, or requirements. These services intentionally provide incorrect details to discourage voting or cause confusion about the electoral process.
Political donation fraud: Fake political organizations and candidates set up fraudulent donation sites that look legitimate but funnel your money and financial information directly to scammers. These sites often use names similar to real campaigns or causes to deceive donors.

Your role in protecting election integrity

Every voter plays a role in ensuring elections remain fair, secure, and transparent. By following proper voting procedures, verifying information through official sources, and reporting suspicious activity, you help strengthen trust in the system. Small actions can make a big difference in protecting the integrity of every vote.

Plan your preferred voting method: Before Election Day arrives, take time to plan how you’ll cast your ballot—whether it’s in person at your local polling place, by mail, or through accessible voting options available in your state. If you’re an overseas military or citizen, research your state’s UOCAVA procedures. Knowing this could help you avoid last-minute issues that might force you to bypass safe voting practices.
Confirm your voter registration status at your official state portal: This quick step ensures that your information—such as your name, address, and polling location—is accurate and up to date, and helps you avoid surprises like being listed under the wrong district or finding out you’re not registered at all.
Verify your polling location through official channels: This ensures you’re voting at legitimate facilities with properly managed systems. When available, choose paper backup options or locations that use voter-verified paper audit trails, which provide physical evidence of your vote that can’t be altered digitally.
Keep your personal devices secure during election periods: You can do this by updating software, using strong passwords, and being cautious about election-related apps, websites, or messages that aren’t from official government sources.
Stay alert for potential vulnerabilities: As a voter or observer, you can: verify polling place seals are intact, confirm machines display zero totals before voting begins, observe that poll workers follow proper procedures, and report any irregularities to election officials immediately.

Key tips to verify legitimate communication during election season

Practicing good cybersecurity hygiene helps safeguard not only your information but also the integrity of democratic participation. Here are some key guidelines to stay secure online and protect your vote.

Official election information only comes from verified .gov websites: Scammers often create legitimate-looking websites to trick voters into sharing personal data or clicking malicious links. When searching for election details, always rely on official .gov domains. These are verified and maintained by state and local election authorities, offering information that is accurate, secure, and up to date.
Contact your state or local election office directly using official phone numbers: For voting-related questions, contact your state or local election office directly using details listed on verified .gov websites to ensure you receive accurate local information. Do not rely on social media, emails, or unofficial websites, as scammers often use these fake hotlines to collect personal data or sow disinformation.
Deal only with verified election officials: Imposters may pose as officials through phone calls, emails, or even in person to collect your personal data or influence your vote. To confirm legitimacy, check any communication from an official .gov email address or website, verified government phone line, or your local election office.
Verify “urgent” voting information through multiple official sources: During election season, scammers often spread “urgent” messages or “breaking news” to sow panic or confusion—such as changes in polling hours or locations—to suppress voter turnout. Always verify updates through official sources, such as your state’s .gov election website, local election office, or trusted news outlets.
Update all your devices with the latest security patches: Before researching candidates, browsing election information, or logging into voter portals, make sure all your devices are running the latest versions. Security patches fix vulnerabilities that hackers can exploit to install malware or steal personal data.
Use strong, unique passwords for voter-related accounts or portals. When creating strong, unique passwords for each election-related site you use, especially government or voter registration portals, use a mix of letters, numbers, and symbols, and avoid personal details like birthdays or pet names. Password managers can help you generate and store complex passwords, reducing the risk of credential theft.
Enable two-factor authentication (2FA) wherever possible. Enabling 2FA on your email and voter-related accounts significantly strengthens your defense against unauthorized access. Even if hackers obtain your password, they won’t be able to log in without this additional confirmation.
Report suspected election-related scams to your local officials and relevant authorities: If you encounter a suspicious website, message, or phone call related to voting—report it to your state or local election office, the Cybersecurity and Infrastructure Security Agency or the Federal Trade Commission. Authorities track malicious activity and protect other voters from falling victim to similar schemes.

These multi-layered protections work together to maintain election integrity, though gaps can emerge when procedures aren’t consistently followed or when oversight is insufficient.

Final thoughts

While online voting systems can’t be written off, ongoing cybersecurity challenges don’t bode well for the immediate future of these platforms.

While technology has transformed nearly every aspect of modern life—from shopping to banking, and working—applying that convenience to the voting booth still presents challenges. Security, transparency, and public trust remain at the core of any democratic process, and rushing toward online or paperless voting without upholding these principles could be harmful.

Progress is steadily being made, however, with advances in encryption and digital identity frameworks. With careful design, rigorous testing, and strong oversight, technology can enhance the safeguards that underpin election integrity.

For now, the most effective way to protect democracy is through awareness and participation. Stay informed about your state’s voting systems, verify election information only through official sources, and remain alert to misinformation and scams. Each responsible voter plays a part in strengthening the integrity of elections.
