I'm surprised there any Ds left to switch down anywhere in Old, Deep South. Leaving the dems to join the GOP. It sorta sounds like a typical lottery winner thing to do, doesn't it?
This is the fourth Louisiana State Representative to switch parties since November. They a) don't want to be in the minority when they've grown accustomed to the power, and b) don't want to be screwed over in redistricting (and plenty of legislators will be screwed; the huge post-Katrina population shift means basically the entire map will need to look different).
