The Obama campaign has a nifty, Katamari Damacy-esque website where you can register to vote quickly and easily, unlike the McCain campaign, which could only conceivably win if they were to actively discourage new voters from registering. I followed the instructions and was able to register to vote absentee in my county in about 10 minutes tops. I think the process for normal voting is a bit shorter, since you don’t have to take a detour through state and then county websites. (Via Bitch, Ph.D..)
