A Chicago dentist is paying for a new ad advocating that Secretary of State Hillary Clinton make a second presidential run in 2012.

Clinton, who accepted the top diplomat's job under Obama after her Democratic rival's victory in 2008, has said she will not run for president again.

The ad initially aired Wednesday in New Orleans, according to CNN, which first reported the story.

'She has more experience working in and with the White House than most living presidents,' the text of the ad reads. 'She is one of the most admired women in our nation's history. Let's make sure the president we should have elected in 2008 will be on the ballot in 2012.'

The conclusion of the ad comes with a slogan: 'Hillary 2012: Hillary Clinton for President. Start now. Where there's a Hill there's a way.'

The dentist, William DeJean, told CNN Thursday that he hopes to also air the ad in Washington, New York and Los Angeles.

He also said that he paid $5,000 to create the ad, though it's not clear how much he will pay to air it.

According to a search of the Federal Election Commission database, DeJean made several contributions to Clinton's run for the 2008 Democratic nomination, though $2,563 of the total he donated was returned after her campaign ended, Politico said.

In all, only $737 of more than $3,000 he tried to donate to Clinton ended up in her presidential coffers.

'I'm a dentist, and I don't think this country is headed in the right direction,' DeJean told the network.
