If you support Obama, be sure you actually get to the polls and vote tomorrow. Even if it's a pain. Even if the line is really long. Even if you think your registration may be challenged. Even if you think your vote won't really be counted. If they give you the runaround -- hiding your polling place, or telling you you have to go to a different one, or saying the machines are down -- don't give up until you actually get that vote in. The election is rigged, but it's really only a little bit rigged -- a few tens of thousands of votes in states with millions of votes cast. They can only steal so many votes. If we all vote, we will still win, because we can cast more than they can steal. They'll only win if enough of us just give up and let them.
Vote. If you can help someone else vote, do that too. It still matters.
