I tried to look at this from as many angles as possible. My opinion... there is nothing to read out of this. He is here because he can afford to be. The only thing that would qualify as an answer at this point is if some massive scandal that we don't know of is about to break, in which case, there is no point in speculating right now.
I want to think there is a chance we might get back into this thing, but I'm just not seeing it. Something would have to happen in the next to totally change the dynamics of this race. McCain has run a terrible campaign. He turned the wrong way around every corner.
boy its good to see one republican pennsylvanian not making too much out of Obama's PA tour...
