It's a "trickle-down" effect. Southern states started voting for Republicans at the Presidential level decades ago ('50s/'60s), then Congressional/Gubernatorial ('60s/'70s/'80s), followed by legislative and local ('90s/'00s). It doesn't happen overnight. AL will have a GOP legislature eventually, but it may take as long as another 20 years.
Louisiana will see two thirds of its legislature term limited out in 2007. I don't think we can gain control, but I think we can make big inroads.
20 years?? Egads, we can't wait that long. Oh the horror. :) Seriously, it will be a relief when it does happen. There are some legislators who really need to be expunged from office.
