has to win and two states that two weeks ago seemed to be trending ever so slightly to romney. so what about all this talk of expanding the map? most campaigns are now advertising in three new normally reliable democratic states but they're leaning democratic states. let's not pretend they're solid. then this morning a new detroit news poll of likely voters has in michigan showed the president leading romney but only by three points. a new franklin and marshall poll in pennsylvania shows the president up by just four points. this week a minneapolis star tribune poll showed a three-point race in minnesota. the romney campaign says this is evidence they have expanded the map. the obama campaign says this expansion of advertising shows it's a sign that romney has run out of routes to 270 electoral routes in the nine battlegrounds and needs more ways to get there, so they're throwing hail marys.
