Why Gallup Ignores Party ID

Gallup editor in chief Frank Newport explains why party identification isn't a factor they take into consideration in doing their polling.

We do not weight by party at all - we never have and we don't now. We think party identification is an attitudinal variable that fluctuates just like who you're going to vote for...


When criticizing polls, people point to the number of people tallied from each party as a sign of bias, so Newport's explanation is intruiguing. Before the first debate, when Obama lead, the right was complaining about methodology, but with Gallup consistently showing Romney ahead by 6 points, now the left is mad.
