i know this isnt the right forum for this, but i figured i might as well do someone a favor.
i have no idea how accurate these cnn polls are, so i have no intention of betting on this myself, but if the polls are anywhere near accurate then political betting lines are not correctly reflecting these polls.
according to those polls obama, edwards, mccain and gingrich are all +ev bets:

ftr, i have no money invested in this and dont plan to bet on the election at all.
