In Mississippi's hotly debated Senate race to complete the final four years of a six-year term left vacant by Republican Trent Lott, Roger Wicker's campaign against Democrat Ronnie Musgrove is playing up gay stereotypes and bashing gay marriage.

A new 30-second spot that appeared this week ridicules gay Americans with offensive stereotypes.

In the ad, a Democratic Senatorial Campaign Committee (DSCC) Musgrove fundraiser says, “We got a shot at defeating a conservative pro-life Senator.” People immediately line up to donate money, including a woman representing the Friends of Hillary Clinton PAC and a creepy-looking man representing the NARAL Pro-Choice America PAC.

“Let's go. Ronnie Musgrove has promised to support our liberal Democratic leadership,” says the fundraiser as the line continues to move along swiftly.

Actors portraying the Human Rights Campaign (HRC) PAC – the nation's largest advocate for gay and lesbian rights – step up to donate: One man is dressed as a cowboy and another in leather representing the 1970s disco band the Village People – an outdated and insulting gay stereotype.

The text reads, “HRC SUPPORTS GAY MARRIAGE.”

“We just thought it would be in good fun to show Mississippians who's paying for these ads,” Wicker campaign spokesman Ryan Annison told The Associated Press.

The ad is not only insulting, the charges are also false. Musgrove is neither a pro-choice nor pro gay marriage candidate. And neither the Human Rights Campaign PAC nor the NARAL Pro-Choice America PAC have donated directly to the Musgrove campaign, reports The Associated Press.

“That sounds like an ad, to me, of somebody who's worried,” said Marty Wiseman, director of the Stennis Institute of Government at Mississippi State University.

Wicker is currently filling Lott's Senate seat until the November election.
