The odds aren't "terrific". They're mathematically impossible.
Romney sent a message to mccain. “Don’t forget the businessmen. Don’t forget immigration.”
Huckabee sends a message to mccain. “Don’t forget the working class. Don’t forget to be strong on values and overhauling the tax code.”
A vote doesn’t always get the person you voted for but it can influence IDEAS
Nothing is impossible... I believe Romney’s delegates are now free to go wherever they want. If they were all reallocated to Huckleberry (however unlikely) we’d have ourselves a horse race again... well, more like a donkey race.
