From TPM Reader RF ...

I'd have to agree with the first responder. Sestak is my representative as well. I donated money and worked hard for him in 2006. In 2008 I did neither because on some issues important to me (the war and whether anyone in the white house should be punished for criminal actions) he was a big disappointment. He's very middle of the road on many things. However, if he opposed Specter for the nomination I'd donate and work for him again because he would be a *much* more reliable vote for so many important Democratic issues. There's just no contest.

Arlen Specter thinks he's a middle of the road moderate because he says one thing and then votes the opposite and he believes that somehow balances things out.
