Game On: First 'Hillary 2012' Ad Hits the Airwaves

As President Barack Obama's approval ratings continue to stagnate, Democrats' grasp on the White House in 2012 continues to loosen.  Though a lot can happen between now and then, some Democrats have already jumped ship from the HMS Obama, and are instead seeking political refuge with a familiar player in Democratic politics, Hillary Clinton.

The first televised ad for a Clinton-for-President recruitment campaign has officially hit the airwaves, courtesy William DeJean, a Chicago dentist who tells CNN he thinks the former senator and acting Secretary of State is the "most qualified" Democrat to run in 2012.  “I’m a dentist and I don’t think this country is headed in the right direction," he says.

And what about Chicago's own hometown hero?

DeJean adds that he thinks people are having buyer’s remorse about President Barack Obama and says the current administration is ruining the Democratic Party.

DeJean's ad is currently receiving air time in New Orleans and is planned to run in other major cities, including Washington, New York and Los Angeles.

Unless Obama steps down from a run at a second term -- something highly unlikely -- Clinton fans shouldn't get their hopes up.  Earlier this year, DNC chairman Tim Kaine insisted the Democratic Party would renominate both President Obama and Vice President Joe Biden in 2012.  Still, there are historical precedents for an intraparty challenge to a sitting president.  In 1968, Eugene McCarthy gave then-Presiden Lyndon Johnson a run for his money; Ronald Reagan challenged incumbent President Gerald Ford in 1976; Ted Kennedy gave a spirited try at unseating weakened President Jimmy Carter in 1980; and Pat Buchanan challenged Bush 42 in 1992.

That said, anything can happen in American politics.
