Following last night's huge win in Mississippi, the Obama strategy is, in a nutshell, to play down Pennsylvania, thus eliminating the media suspense behind it. According to the campaign this morning, Obama will also campaign early and hard in North Carolina. This doesn't mean he is writing off Pennsylvania. He will campaign hard there too. But just think -- if Obama loses both Pennsylvania and North Carolina, he is in big trouble. Better to campaign for both now, rather than putting all the eggs into one basket and doubling down on Pennsylvania. The campaign believes that the number of delegates gained by a Hillary victory in Pennsylvania can be offset by wins in the other contests.
