Cruz would have lost to Hillary.
You mean, Trump almost lost to Hillary because many Republicans with any sense of manners wouldn't vote for him, so voted for Hilary instead or just stayed home. I think that is what you mean.
I myself was sort of that mind, but bit the bullet and voted for him anyway because I thoroughly hated Hillary, for her criminal actions that were not being penalized (and are still not due to DOJ), and all that she stood for.
Now, we've got even worse.
We'll never know, and you cannot say, that many decent fundamental Christians might have come out and put Cruz in. But if not, I'll speculate that with Hillary's known record, and a Republican=dominated Senate, she would far more easily been controlled than Harris will be now, with both the Senate and the House in hr power, once Biden goes down. And that is likely to be soon.
I guess I don't have any reason to admire your perspicacity, do I?
