If Obama agrees to another debate there is an increased chance of a game-changing gaffe. If Obama does not agree to a debate, Clinton will use that fact to raise doubts about Obama’s potential as a general election candidate.

Clinton herself offered this assessment before the polls closed. "I think a win is a win…I think maybe the question ought to be, why can't he close the deal with his extraordinary financial advantage? Why can't he win a state like this one, ... states that Democrats have to win."

Looking ahead, Rasmussen Markets data gives Obama a % chance of winning May 6 in North Carolina. Indiana also votes that day and looks to be more competitive—Clinton is given a % chance of winning among the Hoosiers while Obama has a %.
