He needs enough of the American public behind him to get what he wants done. I have no doubt that he has much more public support than any of the MSM want us to believe, but he may need more to get the likes of Boehner to stand with him instead of folding and crumpling.
The MSM and the democrats fear Cruz. The Republicans are holding the line and Cruz is leading the charge.
Cruz was very impressive today in the interview with Crowley and Boehner did real well in the interview with Stephanopoulos.
