If you're in America, go vote. If you already voted, tell someone else to vote. Check especially the outliers...the younger students who might never have voted before, newer Americans, people who have just moved to your area.
If you're not here in America, call us up. Make sure all your friends here have voted. Send off some emails. Plead for your favourite candidates. Why not? The actual candidates have done a lot worse. I feel it's totally okay as long as it's not family.
Have an older relative who might struggle getting to the polls? Drive 'em. (Call first.)
Then treat yourself to some chocolate.
We should all be represented these next four years.
