Why bother with a party id survey and then ignore it?
That’s the question. I can think of three answers:
1 - By weighting it differently, the race becomes tight and we spend time on his site, people sign up and he makes money.
2 - Political pressure by the Obama camp to not show the race as a Romney lead
3 - Peer pressure to not show the race as a Romney lead in order to keep in line with the other polls
You forgot the added pressure of the fact that the Obama administration is suing Gallup after they reported that that Romney was ahead,
