Someone on Fox just quipped that anyone who is undecided at this late date is unlikely capable of finding a place to vote let alone casting a ballot.

I wouldn't count on it. These are the people the Dems pick up in a big bus, drive to the polls, give a quick lesson on who to vote for (except when they screw up the instructions like they did in FL last year), and then take out to celebrate at an "after-the-vote" party.
