Well, this could get interesting: The Louisiana Web site PoliticsLa.com reports:
David Duke is back home after a year-long "vacation" at a federal prison in Big Spring, Texas, and he hasn't slowed down a bit. ... There is no prohibition stopping a convicted felon from running for any federal public office. ... He's quietly telling friends that a Senate campaign is more to his liking and fits his current agenda well.
... a U. S. Senate race has nationwide interest, and Duke is telling friends he can generate significant campaign funds all over the country.
Duke opposes U.S. involvement in Iraq -- he's obsessed with Jews and Israel now; as you can see from his Web site, he thinks "Jewish supremacists" got us into the war. That means he won't get a lot of the pro-Bush vote -- but we don't know how many really-out-on-the-fringe voters there are in Louisiana who might vote for him anyway.
The state has open primaries -- everybody runs at once, and the top two vote-getters go to the general election if no one gets a majority of the vote. I'm guessing it won't happen, but if Duke and a Democrat survive the runoff, and Duke is alienating Bush supporters, the Democrat wins easily.
