The establishment is giddy about the Rubio strong showing. They now have their man. They were scared to death that they were thinking they might have to ride with Trump. Those fears are over. Rubio is going deep in this race and might just win.
I can't always agree with Trump but he is authentic as his own man. Cruz is authentic about his ideals probably because he was raised that way by his holy roller dad. Rubio? To me Rubio calculated that the GOP needs a token hispanic and he is Cuban and that was his way in and he could get far playing that hispanic card.
