PEARL, Miss. (AP) — They’re not exactly rooting for Barack Obama, but prominent white supremacists anticipate a boost to their cause if he becomes the first black president. His election, they say, would trigger a backlash — whites rising up, a revolution of sorts — that they think is long overdue.

He’d be a “visual aid,” says former Ku Klux Klan leader David Duke, in trying to bring others around to their view that whites have lost control of America. Obama’s election, says another, would jar whites into action, writing letters, handing out pamphlets rather than sitting around complaining.

While most Americans have little or no direct contact with white supremacists, organizations such as the Anti-Defamation League and the Southern Poverty Law Center keep close tabs; the law center estimates some 200,000 people nationwide are active in such groups. These observers think the prospect of a white revolution is fantasy.

White supremacists — many call themselves nationalists or “White activists,” with a capital W — have had limited political success: Duke served in the Louisiana Legislature. And the public has periodically been unsettled by their public events, like the effort by uniformed Nazis to march through Skokie, Ill., the annual Aryan Nations meetings in Idaho and elsewhere or the FBI’s clashes with armed white supremacists in several Western compounds.

Richard Barrett is a 65-year-old lawyer who traveled the country for 40 years advocating what he perceives as the white side in racial issues — like his January rally in Jena, La., to support a white teenager who hung a noose in a school yard.

Barrett is convinced Democratic Sen. Obama will defeat Republican Sen. John McCain in November.

And that could cause an upheaval, Barrett, a leader in the Nationalist Movement, told The Associated Press in an interview at his rural Mississippi home.

“Instead of this so-called civil rights bill, for example, that says you have to give preferences to minorities, I think the American people are going — once they see the ’Obamanation’ — they’re going to demand a tweaking of that and say, ’You have to put the majority into office,”’ Barrett said.

Across the United States, some white supremacists are saying an Obama presidency could create a racial backlash that will give their groups a boost.

Barrett is evasive about his ideology and tries to keep reporters from using “buzz words” to describe him. He doesn’t call himself a white supremacist, although the Anti-Defamation League and the Southern Poverty Law Center do.

The law center tracks the Nationalist Movement, the Klan and like-minded groups from its Montgomery, Ala., headquarters. The center’s “Hatewatch” newsletter reported in June that some neo-Nazis, Klansmen and anti-Semites are saying an Obama presidency could prompt a race war, which many on the “radical right” believe whites would win.

Although not all white supremacists agree, “large numbers of these people really seem to think that an Obama election would benefit them hugely,” Mark Potok, the center’s intelligence director, said in an interview. He called that view “essentially a fantasy.”

Duke, the former Klan leader, posted an essay on his Web site in June titled, “Obama Wins Demo Nomination: A Black Flag for White America.”

Obama “will be a clear signal for millions of our people,” Duke wrote. “Obama is a visual aid for White Americans who just don’t get it yet that we have lost control of our country, and unless we get it back we are heading for complete annihilation as a people.”

Jason Robb, a Harrison, Ark., attorney who represents the Klan’s Knights Party, describes himself as a “white nationalist.”
