Vote.

From Mitch:

In the movie WarGames, the computer realizes that the only way to win a nuclear war is not to play. Voting is the opposite: the only way to lose is not to play. So please go out there tomorrow and cast your ballot for whatever candidate you think is the best choice, based on their stated policies. Every election is important, and this one is no different. Nothing else you do all year will matter as much.
