Could get interesting if he loses again in a close way - in the end an election is a tally of who'll likely win if it comes down to cold steel, so as to avoid the unnecessary loss of men by the same cold steel, as the superior numbers usually obtains victory. Certainly makes more intuitive sense in a state where voting is NOT compulsory. A lot of Trump's "deplorables" would throw down if given the merest solemn undertaking of legal protection upon victory.
In a pitched battle no doubt Trump's supporters (typically men with a penchant for guns, lots of them veterans) would require much, much, much much..... much, much, MUCH less than 50% in numbers to neutralise the opposition.
