A March 2 MRC "Media Reality Check" by Tim Graham lives up to our prediction that the MRC would continue to dishonestly attack a CBS News poll showing record low job-approval ratings to President Bush.
As the blogosphere quickly discovered from CBS's online report, CBS "weighted" its sample to reflect an ideal cross-section of American adults. They adjusted the number of self-described Republicans up to 28 percent and Democrats down to 37 percent, and independents with the rest. That's hardly the exit-poll breakdown the networks found on Election Day 2004 (37 percent GOP, 37 percent Democrat, 26 percent independent).
Graham fails to tell his readers that the Democrat-Republican ratio of the CBS poll closely mirrors the general population of registered voters, as Republican strategist Rich Galen pointed out in a March 1 column at MRC sister site CNSNews.com. Graham also does not explain why a poll methodology based on registered voters is less valid or accurate than one based on likely voters or one based on the voter ratio of the last major election.
Instead, Graham dishonestly attacks the CBS methodology as "biased" despite the fact that there is a solid, logical methodology behind it.
