MARK HALPERIN, BLOOMBERG POLITICS: The one thing they like about her on substance, she's moved to the left. People like Elizabeth Warren have forced her to go to the left. They would like a progressive president, but they also want to hold the White House.

But they like the fact that they think the Clintons know how to win.
