If you're eligible to vote and chose not to push a button, or draw a line, or check a box, or fill out an absentee ballot…. why? If you chose not to vote and then complain about ANYTHING during the next few years – then I hope you get hit by a bus. A bus with pointy spikes all over it.
Even if your vote was stupid (like voting for McCain), at least you took the time and made the effort to have your views and beliefs better represented in our government. I know 2 people that admit to voting for McCain, and 4 that didn't vote – one of which is proud of the fact that he didn't vote. I'd rather know 6 people that voted for McCain.
