You could be right, it would be especially helpful to Cruz if Rubio left the race. But what does that tell you about the “true conservative” Cruz? I’m astonished that people don’t see Ted’s establishment ties.
It tells me nothing. It's not binary.
Matter of fact, it probably has as much to do with people not liking/not trusting Trump.
And you can't assign traits to a candidate from the characteristics of their supporters.
You wouldn't want that done with Trump, would you?
