If you don't know anything, go stick your head in an oven and turn it on. BTW, that would be a gas oven for those of you who really don't know anything.
Today is the last day to register to vote in California.
Learn. Check out the official voter guides. Check out voter guides from different media organizations (as many as you have time so you can make sense of every one's bias and make a sensible decision). Oh, and watch The Daily Show with Jon Stewart, the only player in this election with no credibility gap (mainly because they don't claim to have any)..
Vote. Vote by abseentee ballot (legal for anybody in California), if you're not capable of getting to the polls on election day, or if you don't trust the new electronic voting machines.
