Today is the last day to register to vote in the Great State. Info on how to register is here, but you should probably just go to your local grocery store or county clerk's office, given the whole time constraint thing. Somebody will be outside the Wal-Mart registering people. If you're in Austin, the College Republicans and University Democrats will be happy to accost you on the West Mall.
If you don't vote, you are NOT welcome to complain on this blog. I'm just sayin'. :)
