Same as any personality cult, most of what it's built on will fall away without their lord and saviour to keep the lies rolling and distract from the shoddy foundations its built on. Take a look at Brexit over here, there's a hard core who don't want to admit they've been deceived for sure, but more widely, people are exasperated they were taken for such a ride. Over here Trump is seen as very much a part of that same far right cult, indeed Farage has made a big play of his friendship with Trump, and people who you wouldn't expect to wish that on anyone, really aren't afraid to express their disappointment that the guy missed. As time passes, that'll only grow.
