Why does Hillary Clinton keep deploying this awful, forced cackle every time she’s asked a question she’d rather not answer? Does anyone ever laugh along with her, as one would if the questions were actually funny? Even Keith Olbermann’s had enough:

OLBERMANN: Senator, one other question here that pertains to a statement that Senator Obama’s campaign just put out, and we’d appreciate your reaction to it. Let me read it in full: “When Senator Clinton was campaigning in Iowa and New Hampshire, she said that states like Michigan and Florida that won’t award delegates “don’t count for anything.” Now that Senator Clinton has lost badly in South Carolina, she’s trying to assign meaning to a contest that awards zero delegates and where no campaigning has occurred–CLINTON: BWAHAHAHAHA!OLBERMANN: Beyond the laughter, what’s your reaction to that?

Just answer the question. Nobody thinks you think it’s funny.
