John Heilemann checks in with David Plouffe and other Obama advisors:

The Obama campaign's confidence extends well beyond Pennsylvania. In conversations with an array of top advisers this morning, a clear picture emerged that Chicago believes it has Nevada, Iowa, Wisconsin, and New Hampshire more or less in the bag; that it feels nearly as certain of carrying Ohio; and that Obama is just a tad ahead in Virginia. As for Colorado and Florida, Team Obama believes they are both too close to call, but thinks they could well win both; they are forthrightly pessimistic only about North Carolina among the nine battlegrounds. This could all just be spin, of course — or they could simply be proven wrong. But having known and reported on these people for a solid six years now, my sense of their tone and body language is that their self-assurance is for real.
