The conservative Election Projection site (www.electionprojection.com) is predicting a Democratic sweep today.
I go to this site because it's one of the best for giving you all of the necessary info in easy to view maps and summaries. I didn't know they had a conservative bent until after I had been checking in for a while. They are predicting the following:
Senate: Democrats +6 (VA and MO to the Dems)
House: Democrats +25
Governors: Democrats +7
This is one of the few conservative sites predicting such a big win for the Democrats. Let's just hope that because they are conservative they have underestimated the Democratic wave.
