(CNN) – On Friday, the newest negative ad hit the airwaves in Wisconsin – the third such spot launched by a Democratic presidential campaign in three days.
Hillary Clinton’s campaign unveiled an ad Wednesday that took aim at Barack Obama for turning down an offer to debate her in Wisconsin before the state’s February 19 primary, tying the decision to his stands on other issues.
Obama’s campaign struck back the next day with a spot that responded to Clinton’s, calling the original ad an instance of "the same old politics of phony charges and false attacks."
Today, Clinton’s campaign debuted ‘Deserves,’ a response to what it called “false attacks” in the Obama spot.
"Barack Obama still won't agree to debate in Wisconsin,” says the announcer in the 30-second ad, which will also air in Wisconsin. “And now he's hiding behind false attack ads.”
The ad criticized Obama’s stands on issues like health care and Social Security, and asked
“Why won’t Barack Obama debate these differences? Wisconsin deserves better.”
The state's voters head to the polls next Tuesday.
