Interesting. If it's just Kucinich vs. Huckabee with the same economic and general political environment, then the reult is a narrow win for Huckabee, because Kucinich is just too far left to win over the middle:
Kucinich 248
Huckabee 290
But, if Bloomberg gets in the race, it's a whole different story: Bloomberg, with his social liberalism and economic expertise, in this case devours the entirety of the centrist vote in the country and leaves the other two candidates at the margins.
Kucinich 150
Huckabee 81
Bloomberg 307
