They will be mad for a moment and I think in part this is why Richardson endorsed Obama. He is setting up the scene to innoculate himself and hispanics from suffering any of the Obama supporters backlash. Because the super delegates know he is unelectable now due to the reverend problem.

He just is.

Hillary will win in enough key states and be close enough to keep her super delagte lead. With the polls shifting in her favor and his falling.

She will get the nomination.

The Obama backlash will occur. But by Convention time they will be more prepared to accept it.
