Romney + FL, PA, OH, IA is his only hope, even though Pennsylvania is getting harder and harder.
He doesn't need Iowa. FL/OH/PA is 273.
Not if he loses NC, which looks surprisingly likely right now. If he loses NC he'll need a few other small swing states to reach 270.
I included North Carolina (implicitly) as part of the Romeny states. Going for Romney + FL, OH, PA also includes defending NC, possible GA and/or Arizona. But his chances are VERY slim, with no room for error. Iowa is too small to make up for Pennsylvania, and Wisconsin seems further out of reach than Pennsylvania.
