The question: If Carson drops out where do his voters go? If Trump, game over. If not, game on.
I don’t think Carson voters will go to the GOPe candidates (Bush, Rubio, Kasich). They will likely scatter between Cruz, Trump & Fiorina. Unless they realize Fiorina is an insider RINO in outsider clothing. She campaigned heavily for McCain.
