Topic: Accuracy in Media
A March 24 Accuracy in Media column by Roger Aronoff is the latest to attack a CBS poll that found President Bush's approval rating at an all-time low of 34 percent as sampling too many Democrats without noting that the weighted percentage difference of Democrats to Republicans in the poll matches the demographics of the adult American population.
Aronoff also attacks the poll for being "based on a sampling of 1018 'adults,' rather than likely voters," but he fails to explain why a sampling of "adults" is less valid that one of likely voters. After all, Bush is the president of all Americans, not just likely voters. And Bush isn't up for re-election again, so limiting the poll to "likely voters" is a bit on the moot side.
Aronoff further claims, without evidence, that "the number of Democrats was inflated to get a more dramatic anti-Bush result." But as Media Matters noted, a CBS poll taken a couple weeks later in which the weighted percentage of Democrats and Republicans was roughly equal produced the same 34 percent job approval rating for Bush. Additionally, CBS weights its polls based on demographic characteristics, not party affiliation.
