One thing that may or may not make you feel better about that: it's estimated that as many as 40% of voters may already have cast their ballots by Election Day. As of this morning, 5.6 million Americans have already voted.

Traditionally the GOP has had an advantage among early voters, but that changed in 2008 and 2012. This year is shaping up to be the same, I think--though it is hard to know what to make of these numbers, and (I think) dangerous to read too much into them. But I think if an "October surprise" happens around Halloween, there is a good chance it will simply be too late to make any difference.
