Why the polls are bullshit

Seriously. Not wishful thinking. I had heard about this before, but this is the first time I've seen the hard figures, thanks to the leftcoaster.

The Gallup Poll? They poll more Republicans than Democrats. A LOT more.

"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?"
