The best advice I can give is to turn off your tv, computer, and radio (unless you're listening to Rush) for the next 24 hours and focus on one thing: getting to your polling place and voting McCain.
Nothing that the media can say before the polls close means anything. It's all speculation - pro-Obama speculation based on skewed polls at that. Republicans are historically underrepresented in election and exit polls - plus many Republicans will lie and say they voted Obama, while many Democrats will lie and say they're Republicans or Independents who voted Obama. Polls mean nothing, it's the votes that count. We can still turn this thing around!
The media want Obama to win - you know it and I know it. So don't torture yourself watching their spin - it is meant to depress and demoralize you so that you give up and don't bother voting. They'll tell you how bad it looks for McCain and that it will be an early night - maybe inexperienced Obama voters won't go to the polls, but don't let that be you!
They'll tell you about record turnout in heavily Democratic areas - don't listen: they say this every year and this year many Democrats may vote their gut and vote McCain. They'll talk about court orders to keep Democratic strong hold polls open late - again this happens every year and what can we do about it? They'll call races too close to call for Obama - people on the West Coast do not pay attention, get out there and vote McCain no matter how it looks, your vote is important, too!
There will be plenty of time to freak out once the votes start coming in if Obama wins, why stress the whole day over nothing? For your sanity and nerves, stay away from the media until 7 or 8pm - or later if you can stand it - and VOTE MCCAIN!
