Rasmussen is a rolling average, so McCain is susceptible to polls that are weighted in ridiculous-to-believe ways in favor of BHO - attempting to manipulate and control public opinion to reflect what the polls say, instead of the polls reflecting public opinion.

“For polling data released during the week of September 21-27, 2008, the partisan weighting targets used by Rasmussen Reports will be 39.0% Democratic, 33.5% Republican, and 27.5% unaffiliated. For the preceding week, September 14-20, 2008, the targets were 38.7% Democratic, 33.6% Republican, and 27.7% unaffiliated. “
