Hot Air has a great interactive tracking map that has a lot of information available.  It’s a great way to track the results.  I’m not sure what the AP policy is for calling the races, but I hope it is as stringent as some of the news channels’ criteria I’ve seen.

Update: FoxNews.com has a VERY cool interactive map.  It already has some votes up there.  I think it is linked directly to the state databases, because I’ve seen the map change while I’ve been looking at it.
