Nothing short of watching him getting taken down by a smaller opponent and shown for the miserable, narcissistic coward he is would convince his die-hard supporters to abandon him, hence his unwillingness to shake hands with Angela Merkel as he knows she could put him in an armbar and force him to submit in twelve seconds.
There is, of course, Trump’s evangelical base, who welcome his pliability in allowing fundamentalist Christian infleunce on government policy and many of whom sincerely believe that he will be conduit through which the supposed prophecies in the biblical Book of Revelation will come to pass. If you’ve never spoken to such people you should because it is quite clear that he can do no wrong for them as long as he engages in rhetoric which appeals their cause and does things like moving the US Embassy to Jeruselum to provoke the Palestinians. For these people, Trump could literally appear on live television being pissed in by Russian hookers while being sodomized by Vladimir Putin and eating aborted fetus stew, and it would shake their devotion not one iota. Trump is literally everything in diametrical opposition to their supposed values and yet they strump for him anyway.
