For that to happen, most Cruz supporters would have to have Rubio as their number two choice for prez, and not Trump.
As a Cruz supporter yourself, do you really think that's the case?
Yes I do. There is no way after this sore loser man episode that I will vote for Trump in the primary. Trump is unbalanced. A loose cannon. If it is a choice between Trump and Rubio, I’m going with the sane one.
Trump gets about 30% of the Republican vote and that’s it. He has alienated about 70% of the electorate. People who are objective can see him for the egotistical unbalanced blow hard that he is and has always been. Rubio is likeable and he will get most of the center and some of the right. That’s all he needs. With Cruz out of the picture, Rubio coasts to the finish line.
