I've said pretty much all I have to say.
I took #2 son with me when I voted, because he was interested. They said that there had been heavy turnout, but I didn't ask how it compared to 2004. It's Massachusetts, anyway, so my vote didn't count.
If it's close, then we really won't know until late. Florida, Ohio, and Pennsylvania are the keys, and if it's close, then counting will be going on for a while. I hear that Minnesota is in play - if so, this is a bad sign for Obama. More than that, we'll just have to wait and see.
Since I'm not in the middle of fighting off aligators tonight, I plan on tuning into Gun Nuts Radio at 9:00 PM, EST.
UPDATE 4 November 21:20: McCain has conceded, Obama wins.
