Pennsylvania 2012 Why no Romney Effort?

First off, even with Romney's poor polling data, it was clear that he'd have to pick up Ohio, Florida, and Virginia for Pennsylvania to even be in play.  That gets him to 266 right there. At that point there are any number of fourth states that would have put him over the top, of which if you look at things historically, Pennsylvania was among the least likely of those that would have been possible. I think most people would have thought Colorado, New Hampshire, or Iowa would have been likelier to go Romney than Pennsylvania. (As it was, assuming uniform swing, Colorado would have been Romney's fourth state.) So until his campaign began to think of 300 as the goal to shoot for rather than 270, it didn't make much sense to waste time and money in the Keystone State, especially time.

There was a Romney surge following the first debate.

Not really.  Those weren't neutrals that Romney picked up but lean-Romney types who needed either a great Romney debate performance or a poor Obama one to get them to vote for him.  Even f you count that as a surge it was far mre an anti-Obama surge than a pro-Romney surge.
