This viewpoint I find concerning.I hear what you are saying but I cannot agree. The moment I come into agreement that he cannot win, it adds another nail in the cross. Then we both express that opinion and we convince others he cannot win, they add more nails.
We are at war, believe it or not. To deny the only candidate we have, in spite of his track record, is like giving a doomsday speech the hour before D-Day. Why even try?
The apparent religious fervor of his disciples.
How can any Trump supporter be certain that he is the only candidate we have? Now literally that's true of course as he is the only one to declare.
To think of him as so unique that no one could do any better though is a savior complex.
I have never been to war, but this doesn't remind me of any I ever read about. To me, calling this a "war" is like calling Korea a "police action". So I don't believe we are at war, especially the type referencing D-Day.
