You really ought to be getting out and voting today. It’s not a civic duty, but it is a prudent contribution towards your own self-defense and it’s not like it takes that long, anyway.
But if you already have, feel free to engage in some far deeper and more meaningful activities. For example, if you have Flash and a mouse, you can slap the tar out of virtual avatars of George Bush and John Kerry.
Ah, political engagement.
