Why Republicans Say Polls are Wrong

National Journal: “It has become a recurring refrain among some Republican pundits and observers each time a new poll shows President Obama or downballot Democrats doing well: Check the party composition.”

“Critics allege that pollsters are interviewing too many Democrats — and too few Republicans or independents — and artificially inflating the Democratic candidates’ performance. Pollsters counter that the results they are finding reflect slight changes in public sentiment — and, moreover, adjusting their polls to match arbitrary party-identification targets would be unscientific.”
