This is by far the most important thing to remember. Don't forget to vote. Hell, since you're reading this, you've probably already decided who you're voting for (Not PP, but for the only guy who stands a chance to beating him). Go vote early so you don't forget. Or register for mail-in votes.

And don't forget to encourage those you know to vote. Hell, go together to vote as a group. The more people vote, the more likely PP will lose, because almost all the seats he has a decent chance of winning come from the rural prairies, and they live so far apart, it's impossible for them to coordinate in person.
