I can't disagree with your assessment of Cruz's chances of getting either nominated or miraculously nominated and elected.
But, would you agree that having Cruz's voice heard by a wide audience during this nominating process is a good thing for the GOP brand? I'm just trying to find where you're coming from. Sometimes it sounds like you don't like conservatives or their message.
What constitutes "conservatism" has changed over time. When I settled on conservatism as my flavor in the mid 70s we heard Reagan, Friedman, Kemp, and not far before had heard Goldwater.
The evangelicals had been largely Southern Democrats. Reagan won them over. I am NOT from the Southern evangelical branch of conservatism. I am from the modern Goldwater-Reagan libertarian branch, which aligns with my geographic orientation as well. California is often ten plus years ahead of the nation at large, like it or not. I am not making that so, but I accept that it is so.
During my lifetime the Republican-conservative brand has often been self-destructive and dysfunctional. Example: Suthron evangelicals hate Mormons. Yet Mormons are the best voting block which Republicans-conservative forces have, hands down.
Chambers of Commerce represent the companies which employee millions, yet the "in vogue" idea for "conservatives" is to be against the C Of C. Again, self-destructive and dysfunctional.
I am NOT against conservatives or conservatism. I AM against forces which I think are harmful, counter-productive, etc.
Another: Both California and Texas host populations where about 37% self-identify as "Hispanic."
For Republican candidates to be disrespectful towards and about those people, is counter-productive. The idea we will get away with it one more time, in view of demographic changes, is foolhardy.
At the 1992 Republican convention, Pat Buchanan gave a speech in which he was very disrespectful of Hispanics. I disagree with his type of "conservatism," and believe it has been harmful of Republican prospects.
