How much of it is in an NH media market? He might figure that, since he's in NH, he might as well give this a shot.
New Hampshire doesn't have a TV market. It is split between 3 out-of-state TV markets, Boston, Burlington, VT and Portland, ME. Obama is on the air in all three markets. Until recently, Romney was only up in Boston, though he may have entered the other two markets in recent weeks. Even if Romney goes up in Portland, he'd really need to advertise in Bangor and Presque Isle to reach all of ME-02.
