Gallup got a call from the AX man - The Man very upset about honest polling - and then Holder SUED them!
I don’t know much about that. But if they are forcing D/R/I ratios to be favorable to Republicans, then it’s just as invalid as any other.
The bottom line here is party affiliation is not what it was in 2008. A purely random sample will get past that. Or a more recently measured party affiliation mix will.
But using the last presidential election as the target mixture, though traditionally not a bad adjustment, probably is this year. Had 2010 not overwhelmingly reversed it, using 2008 would be much more credible.
Rest assured the Obama campaign knows what is going on and their internal polling is as accurate as they can make it. They make ad buys based on polls and it is not in their interests to use incorrect data.
