Atrios has a bit more on the Louisiana congressman who chose to switch from Dem to Repub in the least honorable way possible. MyDD has more.
I had assumed that Alexander's Repub challenger would be running to the right of the former Dem, but apparently that's not true, at least according to Alexander. He claims that he is MORE conservative than Scott, a long-time Repub. This is actually good news for Dems, who might have felt the need to vote for Alexander as the best of the worst, regardless of his machinations.
Kos has a bit more info on the remaining Dem challenger in this race, Zelma "Tisa" Blakes, of Monroe, LA, who has been described as a "domestic engineer" (the term she used on her registration) and a "businesswoman". Kos advocates sending money, but I'd like to see a bit more about her first. Maybe that's because I come from a state where the Repub leadership recently put up a guy for State Attorney General only to find out a few days later he'd been arrested 19 times (and something about exotic dancing??). Way to go Vancie! Anyway, here's a link to Tisa's upcoming website, which is supposed to be up and running in in the next couple of days.
