In the overall race for the nomination, Huckabee leads with 31 delegates, followed by Romney with 19 delegates and McCain with seven.
On the Democratic side:
Clinton leads with 187 delegates, including separately chosen party and elected officials known as superdelegates. She is followed by Obama with 89 delegates and Edwards with 50.
It looks like Iowa, for Democrats, was not worth a lot of delegates. So the general election could be Huckabee vs. Clinton, afterall.
Huckabee is the only Republican who has successfully defeated the Clinton machine in the past, so I'm sure he'll be ready for the fight.
