(CNN) - Hillary Clinton is taking aim at Barack Obama in a new Wisconsin television ad for not agreeing to participate in a debate there.
"Both Democratic candidates have been invited to a televised Wisconsin debate," an announcer says in the new 30 second spot. "Hillary Clinton has said yes. Barack Obama hasn't. Maybe he'd prefer to give speeches than have to answer questions."
"Like why Hillary Clinton has the only health care plan that covers every American, and the only economic plan that freezes foreclosures," the announcer continues. "Wisconsin deserves to hear both candidates debate the issues that matter. And that's...not debatable."
The ad is Clinton's latest attempt to put Obama on the defensive over his refusal to debate the New York senator more than twice between Super Tuesday and the crucial March 4 primaries in Ohio and Texas. Clinton, who has been widely praised for her debate performances this campaign season, had proposed one debate a week after Super Tuesday.
The Obama campaign later agreed to two debates - one in Ohio at the end of the month, and a CNN/Univision debate in Austin, Texas next week.
The ad is also a sign the Clinton campaign is still aiming for a strong showing in Wisconsin next Tuesday, despite the fact it is devoting much of its resources to the Ohio and Texas primaries a week later.
Responding to the ad, Obama senioir adviser David Axelrod said, "We've debated 18 times, we're going to debate two more, but we've got other business to do here in terms of meeting voters face to face."
