Bush quit, so Rubio will pick up much of Bush's voter base. That is going to make him almost even with Trump. If kasick drops out, Rubio will pick up his base and give him the majority. However, if Carson gets out, Trump may pick up a lot of his votes. It's going to be Trump and Rubio in the home stretch. I think that the more people see of Trump the more they will see that he is a loose cannon. My vote is still leaning toward Rubio. So far, Trump has been hands off on Rubio. Is he thinking that Rubio would make a decent VP running mate when he gets the nomination? If so, a Trump/Rubio ticket would be a landslide win in the general election. The Clintons would finally be handed their walking papers.
