Despite John McCain's disastrous bid for the state in 2008, Nate Silver thinks it might make sense.
My calculations suggest that, despite Romney’s deficit, the upside of his winning Pennsylvania is so great that he might want to take a chance. It’s Obama’s closest equivalent to a must-win state, and the combination of losing Pennsylvania and Ohio would essentially ensure his defeat.
Unfortunately for Romney, it may be too late to adopt that strategy, as Obama has come close to clinching a majority of the state’s electorate in recent surveys.
It's hard to see how making any sort of play for Pennsylvania is smart for Romney.
Obama has led in 20 of 21 surveys in the state this year, and his lead in the RCP average of Pennsylvania polls currently stands at 8.4%.
Democrats have a massive registration edge, it's enormously costly to wage a statewide campaign there, and it would take many millions of dollars to start making any sort of dent in Obama's lead.
