With this new Rasmussen poll showing Coors ahead, 49-48, it begins to appear as though the Rocky poll showing Salazar up by 11 points was an outlier. Coors had released a Tarrance poll showing him down by 2, following a Tarrance survey showing him down by 4. Salazar's internal poll had him up by 5, so it's possible that the Rasmussem poll, too, is a little over-optimistic.
Still, the poll was conducted on one day, September 16, after the first debate but before the Saturday appearances and debate, and would confirm a trends in Coors's direction, or at least a tightening of the race. (The distinction is important. The state-by-state Rasmussen presidential polls are compilations over a month of data from that state, collected during the national presidential survey.) Interestingly, the Rocky poll claims a +/- of 4.33%, while Rasmussen claims 3% accuracy.
Only the Salazar poll released its party registration numbers, which seemed to accurately reflect the state's balance. I've emailed the Rocky's reporter, Lynn Bartels, and asked her where I might be able to get those internals.
