But seriously, I love the idiots that think Biden "locks up" PA. Sadly, Biden would likely win here very easily (assuming no major gaffe) if he was the Presidential nominee. He's the running mate. He's not going to make a big difference here.
Well, in Biden's defense he is an older, more Catholic VP and Pennsylvania is an older, more Catholic state. So he might be an "ok" surrogate for local media and probably one of the better VP choices for Obama in this state.
I mean, we're talking tenths of a percent here though.
