Who Will They Decide To Cover? McCain or Obama?

From John "The Granite Status" DiStaso: "Illinois Sen. Barack Obama will return to New Hampshire for his second campaign visit March 16. No details yet, but the campaign is working on them as it continues to set up its state headquarters on Rogers Street in Manchester." It appears that March 16th will be the day of rock stars in New Hampshire. Will the national press decide to cover Obama or McCain?
