Where will Edwards' supporters go?
By CNN's count, Clinton has 232 committed delegates, she needs 2025 to win the nomination, and there are 3598 delegates left to be decided. All she has to do is win 50% of the remainder, and she wins outright.
Obama has 158 committed delegates. He would have to win 52% of the remaining delegates to win the nomination outright.
The Dems more or less are awarding their delegates proportionally, so the % of support is a pretty accurate gauge of potential delegate wins.
The latest poll averages (with Edwards in the mix) have Clinton at 42%, Obama at 33%, and Edwards at 13%. Unless the Edwards supporters go with Obama in near unanimity, Clinton may have the nomination sewn up.
