“WARNING: Any person who, by use of force or other means, unduly influences an elector to vote in any particular manner or to refrain from voting is subject to a fine.”
And that is from the ballot they mailed to Oregon residents. I would think selling your vote might fetch you some trouble.
As far as I know, this is a federal felony. I was just listening to a story on NPR a few weeks back where the first person who tried to sell his vote on ebay (as a joke) had all these federal agents investigating him, he was on the cover of NYT the day after he posted it…it wasn’t good.
Well, to answer both questions, yes you can sell your vote, and yes it is illegal. In the same way, yes you can jaywalk or smoke crack or murder someone, but you would be likely to face legal consequences should you get caught doing so by someone willing to throw the book at you.
