He's right. Go google "poll guns http://wgnradio.com/" and the only thing that comes up is pro-gun sites. The opposition undoubtedly used email to organize their campaign or was a handfull of kiddies with a polling script.
His implication that the numbers were skewed by gun owners only is absurd on its face and to his accusation that "they'll do anything to get their way"... I say "pot, kettle, black"... They're depending on peoples general ignorance of these polls and the internet in general to sell this line.
