Richardson endores Obama at this stage in the nomination process. Even though it is Easter we all know how “forgiving” Clinton will be. I am thinking for Richardson to make such an endorsement now means that he believes that Obama has the nomination locked up or that by his endorsement it puts Obama over the top.
I doubt that if Richardson would have made the endorsement if he thought Clinton had much of a chance to win.
I think Richardson has just sent a signal to everyone-Clinton is toast!.

That's how I read it too - I don't think Richardson would have parted ways with the Clintonistas unless he felt certain that Shrillary is toast. Of course, Obama may be toast now that his loony racist minister is in the picture!
