I am gonna go with Haralabos making one bazilliondy dollars solving the NBA.
EDIT: I guess Nate's stuff is pretty influential now that I think about it. Sports >>> lol politics though. And if Haralabos published his work instead of hoarding it to be rich, he'd be super influential in that regard.
1. Nate Silver
2. Top poker guy on 2+2 (not sure who this would be)
3. Hbob (would be higher if more people knew who he was)
4. Michael Weaver
5- more poker guys?
