Obama is getting a lot of Red State endorsements from politicians the last few days. He also got the Kerry endorsement for whatever that is worth. That would not be happening if those people thought Hillary Clinton had the nomination. It is risky for them to make an endorsement against the front runner. Another factor in play is that they think Obama would do better in their Red states.
Would experienced politicians be cutting Clinton if they did not think they could kill her campaign?
Edwards supporters lean toward Obama but most are taking a wait until super duper primary day to see if Edwards can go to the convention as a kingmaker or a compromise candidate.
