I think the only real explanation for Santorum is that he is too conservative for PA.
Perhaps he is. Yet, he's been elected there before. It certainly appears that he will not win this one, though. My point is that incumbency is not a guarantee any longer.
Folks are not happy right now. They're not happy about a lot of things, and I'm including folks from both sides of the political spectrum.
I don't know how things will go on Nov. 7. I'm working for my own state's candidates. But I'm not liking what I'm seeing all that much. I guess we'll all find out in about a month.
