This is important. If you don't vote, you're 100% certain your vote won't count for who you would vote for, and 62.9% sure it will count for someone you you wouldn't vote for (someone else using it in your behalf). If you do vote, you might have a 9.3% chance it will count for who you would want to vote for, which is better than the previous odds. If I were you, I'd vote.
...but your vote "may" count - I say go for it. I suppose you can't write in another candidate for a runoff, eh?
