A Democrat bias in the polls? Statistically, speaking that's bunk

A further note on those American opinion polls. 'Unskewing' polls with party ID is, statistically speaking, bunk | Harry J Enten | Comment is free | guardian.co.uk:
The idea that current polling is 'too Democratic' and needs re-weighting for party identification simply doesn't pass muster. "The mainstream media is skewing its polls with too many Democrats because they want Obama to win." Statements like this one are zipping around the internet a mile a minute these days. The general idea is that there are too many respondents identifying as Democrats in public surveys compared to past elections' exit polls. There's even a website titled unskewedpolls.com that purports to adjust media polls to correct for these errors, based on Rasmussen Reports data. "
