Incompetency is demonstrated as much by what one does not do as much as one does. At this point in time I think because Republicans have not started whole sale jumping ship from Trump demonstrates a lack of competency. I understand the thinking they don’t want to repeat the 1980 Democrat Primary in which Ted Kennedy challenged their incumbent POTUS candidate, Jimmy Carter, but their current course of path is more damaging. At this point in the past the party would have split, with a new, party formed supporting a more viable candidate.
