Promising "to stir the pot," cookbook author Nathalie Dupree of Charleston said Thursday that she'll launch a write-in campaign for the U.S. Senate.

Dupree, who also has written about food for The Post and Courier, said she decided to run because she doesn't think anyone in the race poses a threat to Republican incumbent Sen. Jim DeMint.

"I have one goal in this campaign: to cook Jim DeMint's goose," she said.

But the chances of Dupree or any other third-party candidate prevailing range between slim and none, said adjunct political science professor David Gillespie, who is teaching a course on third-party politics at the College of Charleston.

"Obviously, the quick answer is it's not going to happen," Gillespie said.

The late Strom Thurmond won a U.S. Senate seat by write-in campaign in 1954, but he had served as governor. No other state has elected a write-in candidate to the Senate.

DeMint, who is seeking a second six-year term, faces Democrat Alvin Greene and Green Party candidate Tom Clements on the Nov. 2 ballot.

At least two other South Carolinians have said they also will run as write-in candidates: Mauldin High School teacher Greg Snoad and Mazie Ferguson, an inactive attorney from Sumter.

Dupree said she has $500 in campaign funds but could win with as little as $100,000.

The write-in campaigns emerged after the South Carolina Democratic Party took steps to distance itself from Greene, who has been indicted on a charge of showing pornography to a college student from Summerville.
