I’m not a Cruz supporter and I don’t think Trump is a democrat so your question is senseless.
No problem, he's talking Texan, a variant of English, Spanish, and German. Having lived here 30 years, I'm well versed in it.
Translated, he's merely asking Cruz supporters like me is how do we expect Trump to beat Hillary, if Trump is more of a Democrat than Republican?
A possible answer is the thought of Hillary in the White House is far more loathsome than Trump being the next President.
The one issue I don't see Trump backing down on is the wall on our southern border. I haven't seen any "evolving" on that issue.
