Cruz is Elizabeth Warren’s dream opponent.
Probably true, because Warren's one note pitch is against big bankers, and Heidi has worked for both Merrill Lynch and Goldman-Sachs (which she is currently on leave from to support Ted's campaign).
But, I don't think that Warren is going to run.
Hillary may well choose not to throw that stone, she's living in a glass house. Her son-in-law is a hedge-fund trader / millionaire and the son of a convicted Wall Street tycoon and former Congressman. Pretty amazing, when you stop and think about it.
