Reply #47: More on Rasmussen's Republican bias.

[Perry Logan]

Rasmussen is a Republican firm that regularly asks slanted questions and produces pro-Republican results through a questionable poll weighting method.

Rasmussen regularly has the wildest outliers of all on Bush job approval (typically about 5-7% higher than the average of other polls).

From the start of 2005, Rasmussen has weighted to make Rep and Dem party ID equal at 37%. Yet his table of unweighted data since start 2004 shows that in every month, the Dem figure exceeded the Rep figure, often significantly. This weighting introduces a persistent bias which can be quantified if you know the cross-tab data.
