Secretary of State Hillary Clinton insists she's not running for president in 2012, but that hasn't stopped one of her supporters from rolling out a wishful ad.

William DeJean, a Chicago dentist, says he spent $3,000 to create the first "Hillary 2012" ad, and another $2,000 to begin airing it in New Orleans on Wednesday.

DeJean said the ad will also air in Washington, New York and Los Angeles in the next few days. He said he hopes the ad will give Clinton an incentive to run.

"In my opinion, we need the Clintons back in the White House to fix this country," he told "I don't think we're going in the right direction. I don't like this administration. I think they're ruining the Democratic Party."

"My ad is expressing what everyone is thinking," he added.

The ad is a 30-second ode of pure adulation, with a portrait of Clinton rotating to symphonic music.

"She has more experience working in and with the White House than most living presidents," the caption 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 ad ends by urging viewers to start now, and it displays a slogan: "Where there's a Hill, there's a way."

Clinton was widely considered the heavy favorite to win the Democratic presidential nomination in 2008, but she failed to muster the votes she needed to defeat upstart candidate Barack Obama. When Obama beat Sen. John McCain in the general election, he offered Clinton the secretary of state job.

Clinton has given no indication since Obama moved into the White House that she has an appetite for another presidential bid, and she has repeatedly batted down speculation that she'll run again. But a Rasmussen poll in June showed 57 percent of voters believe Clinton is qualified to be president, compared with 51 percent for Obama.

"There's a lot of buyer's remorse with Obama," DeJean said. "I believe Hillary Clinton is the man for the job. If we don't get the Clintons back in the White House, I don't see a future for this country."
