Curse the fuck out of 'em!
I tend to vacillate between being "if you didn't vote, it's your fucking fault" and "if voting could change anything it would be illegal."
But... the only way you can choose whether to vote or not on election day is if you're registered. There are 1500 elections coming up, and the deadlines to register to vote in them are happening now. Here's a comprehensive list of VOTER REGISTRATION DEADLINES BY STATE. Tick tick!
Also, if you need to register to vote... REGISTER TO VOTE. I'm registered in the Florida Pirate Party, of course.
