David Gergen on what the superdelegates are thinking: "This is not just a question of who can win in the fall. They have to also make sure they held their party together. If at the end of this, the math is against her, she winds up with fewer delegates, fewer votes, and fewer states, if they turn it over to her, they run the very real risk they will drive African Americans out of the party for a generation. And they will drive away young voters. There're some things worse than losing an election in trying to build a party."
