If Cruz doesn’t make it, he’ll endorse Rubio. Rubio is a depressing candidate - most obviously because of his willingness to embrace the establishment on the issue of immigration - but when the alternative is the full-spectrum Progressive-Statist-Crony Capitalist Trump, Rubio becomes the necessary choice.
If which point, those who still care about liberty will have to focus on getting more libertarian constitutionalist types in Congress.
I think Cruz would support Trump over Rubio.
If he supports Rubio, then all I had admired about Cruz was wrong and he was just a GOPe all along.
