Intimidation, coercion, and vote buying

In plain words

Someone who wants to control your vote has two tools: a reward ("I'll pay you") or a threat ("You'll lose your job"). Both only work if that person can check what you did. If they cannot check, the deal falls apart.

The private voting booth is a machine for making checking impossible. You go in alone, and nobody can see or prove your choice.

Voting from home is different. A spouse, a parent, a boss, or a buyer can stand next to you. Technology can help in some ways, such as letting you vote again later so the pressured vote does not count. It cannot fully replace the booth. Public opinions bring their own risk: once you say something in public, someone may punish you for it. That is why sharing an opinion here is always optional and specific.

Defined terms

• Intimidation. Threats or pressure meant to stop someone from voting or to change how they vote.
• Coercion. Compelling a person to act against their will, including forcing them to vote a certain way, abstain, or hand over a credential.
• Vote buying. Paying, or offering to pay, for registering, voting, or voting a certain way.
• Family voting. One household member supervising or controlling another's vote. The Venice Commission says it "infringes the secrecy" of the ballot and must be prohibited ⁵.
• Receipt-freeness. A property of a voting system in which the voter receives nothing that can prove their choices to someone else.
• Coercion resistance. A stronger property. In the definition by Juels, Catalano, and Jakobsson, a scheme is coercion-resistant if "it is infeasible for the adversary to determine whether a coerced voter complies with the demands" ⁹.
• Revoting. Allowing a voter to cast a later vote that replaces an earlier one, so that a coerced vote can be overridden.

Evidence

International standards

General Comment 25 of the UN Human Rights Committee says voters must be "free to vote for any candidate for election and for or against any proposal submitted to referendum or plebiscite ... without undue influence or coercion of any kind," and should "be able to form opinions independently, free of violence or threat of violence, compulsion, inducement or manipulative interference of any kind" ¹. It adds that "any abusive interference with registration or voting as well as intimidation or coercion of voters should be prohibited by penal laws and those laws should be strictly enforced" (paragraph 11) and that secrecy must be protected "including absentee voting, where such a system exists" (paragraph 20) ¹.

The Venice Commission's Code of Good Practice states: "Voting must be individual. Family voting and any other form of control by one voter over the vote of another must be prohibited" ⁵. On remote methods, it says voters "should always have the possibility of voting in a polling station." Postal voting "should be allowed only where the postal service is safe and reliable," and "fraud and intimidation must not be possible." Electronic voting "should be used only if it is safe and reliable," with voters able "to obtain a confirmation of their votes and to correct them, if necessary, respecting secret suffrage" ⁵.

United States federal law, as examples

Federal statutes illustrate how one jurisdiction criminalizes these acts. Under 18 U.S.C. 594, "whoever intimidates, threatens, coerces, or attempts to intimidate, threaten, or coerce, any other person for the purpose of interfering with the right of such other person to vote or to vote as he may choose" in an election for specified federal offices can be fined or imprisoned ². Under 52 U.S.C. 10307(b), "no person, whether acting under color of law or otherwise, shall intimidate, threaten, or coerce ... any person for voting or attempting to vote" ³. Under 52 U.S.C. 10307(c), whoever "pays or offers to pay or accepts payment either for registration to vote or for voting" faces penalties, in elections that include candidates for specified federal offices ³. State laws add their own provisions; this page does not summarize them. See jurisdictions.

Remote electronic voting and pressure

The 2020 joint assessment by CISA, the EAC, the FBI, and NIST recommends "paper ballot return as electronic ballot return technologies are high-risk even with controls in place," and says that where law mandates electronic return, "its use should be limited to voters who have no other means to return their ballot and have it counted" ⁴. Its concerns are mainly technical (integrity, privacy, availability, scale), but it also notes that remote systems often "link the two processes together digitally," joining voter identity and ballot in a way that weakens privacy ⁴. The National Academies' 2018 report Securing the Vote concluded that "internet voting should not be used at the present time" and that "no known technology can guarantee the secrecy, security, and verifiability of a marked ballot" transmitted online ⁶.

One documented mitigation: revoting

Estonia has run internet voting with binding results since 2005 ⁷. Its election authority explains that "during i-voting, a voter can always vote again and change their vote as many times as they wish," that only the last electronic vote counts, and that a paper ballot cast at a polling place takes precedence ⁷. Its reliability guidance says "the purpose of the possibility of changing of an i-vote is the freedom of voting," that "buying of i-votes is a crime, like all other forms of vote buying," and that "transfer of ID-card and its codes is prohibited" ⁸. The same guidance notes a limit: "a voter may not change their vote on the election day" by i-voting ⁸. Revoting helps against a coercer who is present once; it helps less against one who controls the voter's credential or watches until voting closes.

Cryptographic research

Juels, Catalano, and Jakobsson formalized coercion resistance in 2002, considering adversaries who may demand that voters "abstain from voting" or "disclose their secret keys" ⁹. The U.S. Election Assistance Commission's process for evaluating end-to-end verifiable voting protocols requires that "the receipt must not display any ballot selections made by the voter or otherwise enable the voter to prove their selections on the cast ballot to others" ¹⁰. That program concerns polling place systems; its receipt rule shows how verification and coercion resistance must be designed together.

Competing interpretations

Access first versus secrecy first. Remote voting can help people who cannot reach a polling place, including some voters with disabilities and voters abroad. Critics answer that it trades a supervised booth for an unsupervised room. The CISA assessment's position, limiting electronic return to voters with no other means, is one attempt to balance the two ⁴. Advocates of broader remote access may weigh the same evidence differently.

Technical versus social defenses. Some researchers focus on cryptographic coercion resistance ⁹. Others argue that household and workplace coercion is social and must be addressed with law, enforcement, and in-person alternatives. The Venice Commission's insistence on a polling station option reflects the second view ⁵.

Public opinion: transparency versus retaliation. Publishing opinions can make debate more honest and representatives more informed. It can also expose people to employer, community, or online retaliation. No law fully prevents social punishment for lawful speech. This framework therefore keeps opinion sharing voluntary, specific, and optionally unnamed. See opinions.

Application to this framework

1. No proof of a ballot, ever. There is no ballot share button, no vote history, no "I voted for" card, and no person to ballot research product. The demo's "I VOTED" card does not exist, because no official vote is cast; a future participation card could confirm participation only, never choices. See private voting.
2. Opinions are not ballots. A public opinion snapshot is labeled as an opinion. The framework never infers a ballot from an opinion, so a coercer cannot use a public opinion as proof of a vote. See opinion and choice.
3. Remote official voting is a research problem. Any future official remote channel would need jurisdiction-specific legal authority, independent evaluation, and an answer to household and employer coercion. Nothing in the demo implements it, and no countdown or button can enable it. See security.
4. An in-person alternative remains essential. Following the Venice Commission's guideline ⁵, the framework treats any remote channel as an addition to, not a replacement for, supervised voting.
5. Credentials are personal. Sharing or selling a voting credential is itself a form of vote buying, as Estonia's guidance recognizes ⁸. Device-level protections help but do not prevent a person from handing over an unlocked device; see hardware.

Unresolved questions

• Can any remote design defend against a coercer who is present for the entire voting window? Revoting assumes a later private moment, which some voters may not have.
• How should a system support assisted voting for people who need help without creating a channel for control? See access and exclusion.
• Does public opinion sharing measurably increase retaliation in practice? This framework has no data on that question and makes no claim.
• How would a person report pressure confidentially, and who would act on the report? See governance.
