As far as Senators go, the GOP lineup is pathetic. Vote for whichever - they will lose to Durbin regardless. Psak has a certain screwyness to him, he at least acts like he has read the constitution, which is a plus.
If you live in the 18th district (Peoria or northwest of Springfield) you have to choose between McConoughey, Morris, and Schock to replace Ray LaHood. I went McConoughey because the other two support constitutional amendments on marriage and abortion - on most issues, however, they are similar. Aaron Schock is going to turn into Mini-McCain if he gets into federal politics - I hope he loses the race and stays in Illinois.
