I've pretty much always stuck with: http://electoral-vote.com/ They seem to use the newest polling data to make their current predictions and they were excellent during the 2008 campaign. Which one do you follow?
I tend to check http://fivethirtyeight.blogs.nytimes.com/. Nate Silver's statistical methodologies and derivations of probabilities for alternate events (as well as the now-cast, if the race were to be held today, vs. the Nov. 6 projection taking into account historic trends) are very interesting and informative.
That's a good site. Has there been absolutely no polling in the Texas Senate race since the primaries? I can't find anything even remotely recent. I expect that Rafael Ted Cruz (see what I did there?) still has a sizable lead but I think Paul Sadler is being underestimated. One debate is scheduled for Oct. 2. I really hope people watch.
Me too. I also regularly visit talkingpointsmemo.com which has a poll tracker and realclearpolitics.com for the latest polling averages. But Nate Silver's forecast model is obviously the most sophisticated.
