How do we know that vote selling isn't a big problem in those districts that have wide-spread mail-in ballots? You state that it isn't a big problem, and I certainly haven't noticed anyone complaining, but does that mean it isn't a problem? How do we know how much mail-in ballot fraud is going on? How many reports do we have of such fraud?

I'm VERY scared of giving up the secret ballot. To me, the secret ballot is the basis of the whole system, and without it, the ability to count ballots correctly or not is irrelevant. It seems to me that the human nature of corrupt people makes the lack of a secret ballot just as dangerous as a black-box voting system that can't be examined or recounted. Either way can lead to a well organized and prepared criminal controlling an election.

I think some of your ideas have a lot of merit. Anything we can do to add accountability while preserving anonymity is a good thing.
