The Politico asks an interesting question: "Will supporters of Sen. Barack Obama blame Sen. Hillary Clinton if Obama loses in November?"
"While the point might eventually prove moot, her decision to remain in the race well past the point in which Obama appeared to have an insurmountable delegate lead has nevertheless generated discussion about what responsibility, if any, she might bear in the event of an Obama loss."
One warning sign: There are Jimmy Carter loyalists who still blame Ted Kennedy for his 1980 defeat.
