Voting in another persons name is a felony and there have been a few people who have been caught. Its not worth it, kind of like armed robbery of a mail carrier. Quick way to get fucked by the state.

I believe in Oregon (the pioneer in mail in voting) you’re looking at potential fines or jail time depending, with a potential mix of fraud, forgery, identity theft and other laws being broken.

But the state has this to say:

Is voter fraud a problem in Oregon?

​​​​​​​No. Oregon elections are secure and protected against voter fraud in all but exceedingly rare instances. In 2020, out of millions of votes cast, residents and local elections officials reported 140 instances of potential voter fraud. Of these 140 cases, four cases were referred to the Oregon Department of Justice and two of those are pending resolution.​

By comparison, in 2018 there were a total of 84 total reports of voter fraud. Two were referred to the Department of Justice.

A review of the vote by mail system​ by the state’s Legislative Fiscal Office found from 2000-2019 there were approximately 61 million ballots cast. Of those, 38 criminal convictions of voter fraud were obtained. This amounts to a .00006% rate. ​
