To me, one of the best parts of the 2008 Democratic Presidential Primary was the that the primary became, not a game of momentum and who wins first, but a battle of delegates. While I have no clue who will win in the GOP South Carolina tonight, a win by someone other than Romney will create an extended primary for delegates. In my view this is good for democracy and voters in later states.
Here’s the estimated delegate count so far after Iowa and N.H.: Romney 19
Huntsman has 2 delegates but is no longer in race. 25 delegates are available in South Carolina. 1,144 (!!!) delegates are needed to win the nomination. There are 2250 remaining delegates to win.
