Clinton targets pledged delegates - Roger Simon - Politico.com: "Hillary Clinton’s presidential campaign intends to go after delegates whom Barack Obama has already won in the caucuses and primaries if she needs them to win the nomination."

This is really something. We are not talking about superdelegates, who may have voluntarily endorsed somebody but who are free to vote at the convention for whoever they choose. Clinton is now going after Obama's pledged delegates--these are ordinary folks who pledged that if they were chosen as delegates, they would vote for Obama at the convention. Clinton is playing the hardest of hardball politics now.
