Rasmussen shows a tightening race in New Mexico:

Obama 46 (-1 vs. 6/23 poll)
McCain 41 (+2)

With "leaners" (who don't initially express a preference for one of the major candidates) Obama's lead widens to 6 points:

Obama 49
McCain 43

Looking at this from a VP standpoint, these numbers give weight to Bill Richardson, who could probably hand his state to Obama.
