Trump doesn't need to be competent to do serious damage though. I could go in depth about all the things he could fuck up without his party's support (foreign policy being the easiest and most obvious) but I think I have the best words right here.
Nuclear launch detected.
Okay, fine, I'll go into some level of depth. First off, what is he going to do the first time some kind of international crisis hits? Whether it be Russia invading another neighboring country, ISIS ramping up its expansion, or North Korea having another tantrum, Drumpf will be the one deciding how to respond. When Drumpf realizes he can't sue them, what will he do? He probably doesn't understand foreign policy well enough to pursue sanctions and crap. He will respond with force, I am certain. He will grossly overreact to every crisis and it will fuck things up.
