Gallup polls oversample Republicans
From the left coaster:
Gallup has done it again. After supplying CNN and USA Today with a poll two weeks ago that showed a double-digit Bush lead amongst likely voters that turned out to have a significant bias in its sample favoring the GOP, Gallup did it again yesterday.
Except that yesterday, they not only did it again, they apparently felt that a 7% GOP bias wasn't good enough. So they perpetrated the same fraud upon the media (including their partners CNN and USAT) and voters and this time used a 12% GOP bias in their likely voter screen. I kid you not.
