Glen Reynolds has some notes on the turnout too.
Via Glen: Jonathan Gewirtz has some advice Vote for McCain, He May Win
But, if you can vote, you should vote for McCain despite the apparent odds. You should do this because no one really knows what the odds are. The Obama campaign, the Democrats and the media (but I repeat myself) want Republican voters to believe that the election is a done deal and that voting Republican is wasted effort. They want to discourage McCain votes and votes for other Republicans down the ticket. They are doing this because McCain and the other Republicans still have a chance to win. That chance will be reduced to the extent Republican voters take the Democrats’ advice. Don’t fall for it, vote for McCain.
