Are Today's Polls Clueless?

Frisky070802 writes "As noted on electoral-vote, Jimmy Breslin has an interesting article in Newsday on why polls are broken. This is because they poll only landline phones, and a substantial fraction of younger people have only cell phones -- so they hit a biased demographic. If a majority of younger voters tend Democratic, the polls could be giving Kerry a raw deal. Hmm, could this be why two polls released this week vary so widely?"
