One of the more foolish things I've seen lately is a trend of pundits drawing conclusions about whether campaigns think they can win various states, and therefore whether they have a chance to win, based on whether they've abandoned a state or not.
This was probably never as true as all that. But everyone should know: we're in a new world. The campaigns have plenty of resources. And, meanwhile, there just aren't a lot of states which are going to be competitive in a reasonably close race. At the moment, Pollster rates seven states as toss-ups, another two as leaning to Obama, and that's it. Nine competitive states. The campaigns have the money to contest all nine. And the total swing in them, from four point Obama leads in Wisconsin and Nevada to a two point Romney lead in North Carolina, just aren't all that far apart that it makes sense for either campaign to abandon one in order to play for a longshot. And, indeed, John Sides reports that the candidates are at least running ads in each of these states and a few others, too.
So as far as talk about pulling out of states is concerned...just ignore it. It's all bluff. Both campaigns have the money to compete in all the swing states. End of story.
