I suspect all of the stories about his questionable delegate dealings have dovetailed with that nasty bit of work he did on Dr. Carson. He may have gotten away with that, except now it’s looking like this is his true character.
I think people are realizing that he’s just another sleazy, establishment lawyer/politician. Actions speak louder than words.

In every poll Donald Trump wins the “he-is-who-he-is” factor.
As Lee Atwater would tell you, that’s critically important. Once the broader electorate sense “who you are”, and become comfortable with that sensibility, there is a remarkable shift toward granting the benefit of doubt in policy and change.
[The most recent example of such a benefactor was Bill Clinton in his prime.]
However, in the same polls, Ted Cruz is viewed as the candidate willing to tell you everything you want to hear so long as it benefits him. That’s the “authenticity” issue. Just as there is a long-term benefit in positive authenticity polling, there is a long-term detriment in negative authenticity polling.
Opinions of “authenticity” are almost impossible to change once they embed. The word ‘almost’ is an understatement, because no politician in modern times has ever been able to reverse the authenticity component.
Bernie Sanders also benefits from positive opinions in authenticity, and Hillary Clinton is viewed similarly to Cruz as inherently inauthentic as a matter of mere disposition.
