Gallup Is At It Again - Yesterday's National Poll Had 12% GOP Bias


by Steve

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.

Here is the text from the email I got from Gallup this morning outlining the party ID breakdown in their likely voter samples from their two most recent national polls:

Likely Voter Sample Party IDs Poll of September 13-15
Reflected Bush Winning by 55%-42%

Total Sample: 767
GOP: 305 (40%)
Dem: 253 (33%)
Ind: 208 (28%)

Likely Voter Sample Party IDs Poll of September 24-26
Reflected Bush Winning by 52%-44%

Total Sample: 758
GOP: 328 (43%)
Dem: 236 (31%)
Ind: 189 (25%)

Looking at this, again I have a simple question: how can anyone, especially USA Today and CNN, let alone the rest of the media take a Gallup national poll seriously when Gallup knowingly puts a poll out there for consumption with a 12% GOP bias in its likely voter sample that everyone knows does not exist in the country today or at any time in the last three presidential elections?

Yet this flawed poll showed a narrowing Bush lead from their similarly flawed poll of two weeks ago. So if a poll with an unsupportable GOP bias of 12% in its likely voter sample, shows an 8% Bush lead amongst likely voters when a poll they used two weeks ago with a 7% GOP bias showed a 13% Bush lead with likely voters, then how can anyone not conclude that Kerry is doing much better than Gallup would have you believe?

By presenting these polls with this kind of bias, and then ensuring through CNN and USA Today the farthest possible media saturation, why is Gallup not guilty of engaging in a political disinformation campaign?
