There's been an unhealthy attitude of 'Vote Trump cos it's funny, it's not like there's any chance he'll win anyway...' and it's only now that people have started to consider 'Shit, what if he really does win'.
I dont know where could you have possibly heard that people voted for Trump because he will lose? What I possibly extrapolate from what you say, is that lots of people (at the beginning when Trump had no prospect), would vote for him
NOT because he will win
BUT because they arent fairly represented by the other candidates, no matter if Trump loses or not.
Did the people that have told you they vote Trump coz "funny" were met in a bar or in a video game chat? Because thats not often where people elaborate on political choice.
Trump has charisma and is a good orator, which has been a reason to elect people since democracy was invented by Greeks. It doesnt mean his program is good and that is the weakest point of democracy, that I agree with you.
Trump sometimes is funny, but its only one shade of him.
From what I've heard around the web, what you describe is closer to the anti-Trump reactions.
When Trump had no clear victory path, everyone was like "haha he is a joke and his supporters too XDD LMAO #rekt #notpresidential"
When Trump had a clear victory path, everyone began to be like "OMG OMG he might win, lets kill him? maybe? #killallwhitemen"
If Trump is as bad as some people think he is in term of programs, he wont be re-elected a second time. Thats how democracy works, you make promise, you get elected, you fail, goodbye.
If Trump is einstein as some other think, I really dont believe he will do a full four year terms of purging mexicans with everyone just looking.
Everything seems covered, no need for murder.
