The actress says that holding office isn't in her future

Eva Longoria says she toyed with the idea of running for political office – until she imagined the campaign TV ads confusing her with her role as fiery seductress Gabrielle Solis on Desperate Housewives, she told a group of Latino leaders in Washington, D.C. on Wednesday.

“I’m here today to announce my candidacy for president. … Oh, wrong speech! In the last two years, I’ve had an affair with the gardener and a teenager, I’ve faked a paternity test, my husband went to prison, and I threw him out of a window,” the actress said. “I would probably win in California.”

At the luncheon, Longoria, 31, stressed the importance of supporting arts programs that feature Latino actors. Not that she’s pushing “diversity requirements,” she noted.

The actress, who’s a longtime friend of Dancing with the Stars runner-up Mario Lopez, told PEOPLE: “They didn’t pick him because he was Latin and they needed to fulfill a diversity requirement. They picked him because he’s a good dancer.”

Longoria has been active in politics, including the 2004 presidential race, during which she helped to educate Latino leaders about candidates, participated in a bus tour and met with the Congressional Hispanic Caucus. The actress said she remains informed about immigration, education, health care, and employment issues.

And Desperate Housewives pretty much runs the gamut of American politics. “I think everybody on Wisteria Lane has the money of a Republican, but the sex life of a Democrat so it’s a really political show,” Longoria cracked.
