Hillary Clinton accused Bernie Sanders on Thursday of breaking his pledge against negative campaigning with a new TV ad.
Clinton has begun attacking Sanders daily as polls show the race for the Democratic nomination tightening.
Sanders released an ad in the early nominating states of Iowa and New Hampshire in which he describes “two Democratic visions for regulating Wall Street.”
“We were particularly surprised today to see him break that pledge and run this negative ad,” Clinton campaign manager Robby Mook said.
The ad does not mention Clinton by name but says one vision is it’s “OK to take millions from big banks and then tell them what to do.” The other vision, he says, is his plan to break up big banks, close tax loopholes and make Wall Street pay its “fair share.”
Sanders told reporters in New Hampshire that “They’re mad at me today, they’re mad at me yesterday, they’re mad at me tomorrow. They’re gonna be mad at me for a long time.”
A new poll by the Des Moines Register and Bloomberg Politics showed Clinton beating Sanders in Iowa by 42 percent to 40 percent.
The third candidate, Martin O’Malley, who is down in the polls, called the back and forth between Clinton and Sanders “silly.”
“This type of substance-free silliness is par for the course in Washington and part of the reason why nothing ever seems to get done anymore,” his campaign manager Dave Hamrick said.
