i don't get how ohio's decision to give voters paper ballots of they request one can satisfy anyone. the people campaigning for votes with a paper trail are concerned that a purely electronic vote is not verifiable. if there are paper recordings of a vote, you can do a recount. but with electronic voting machines that don't print a receipt, you can't check to make sure the machines recorded the votes properly.
letting individual voters get a paper ballot if they request one still doesn't give the ability to do a recount of the entire vote if questions are raised about the electronic vote's reliability. because the paper ballots will be given only upon request, only a small proportion of voters will request paper. the remaining portion of the vote would still be unverifiable which means the overall vote numbers will also be unverifiable.
you can't confirm the accuracy of an election result unless you can do a recount of all the votes cast.
