Not saying that I have or would do it but if you want to vote more than once clear your cookie from your last visit. At least I have heard and read that that is all you have to do. But I don't think Ron needs anyone to "cheat" for him.
I'd trust on-line voting over the black boxes all day long.
Well yeah. Personally I believe actual voting on election day should be done on paper ballots and the black boxes should be banned from all elections. Paper ballots are better insurance against vote fraud.
