If Cruz supporters jump to Rubio, their claims of being in it for conservatism were false. Rubio is an amnesty pimp, and if they do jump to his side they were for open borders all along.
Trump is ineligible.
I will agree that Rubio's history on amnesty is just as crappy as the Donald, but other than that Rubio has acted far more like a conservative than Trump has ever pretended to be. Trump has never been, is not now and never will be a conservative.
And at this point, Rubio's stated position on amnesty is virtually identical to Trump's. Not sure that I believe either man right now, but I will give the benefit of the doubt to the lifelong Republican and Tea Party darling of 2010.
I'm hoping that Cruz is the candidate who will beat Trump head-to-head, but if Ted is unable to generate 7 or 8 wins in the next 15 states and drops out, I will move my support to Rubio.
And if the Rubio/Cruz survivor is unable to stop Trump's Idiocracy Express, I will be pulling for a 3rd party run by Mike Lee!
