Odds are bad, but I put one for fun anyway. Ryder.
For future reference, when you have 20 choices, odds start at 19:1 for each. Then redistribute those odds based on what you think the real probabilities for each even is. Total should be 100%. You would take a few percentage off all the odds if you were trying to make money as a bookie. Of course, as a bookie you could always make a poll like you just did and make lots of money off suckers .
