Do none of you understand the constitution? The president doesn't have unlimited power. Trump is a bit authoritarian for my tastes, but not as much as Clinton. Additionally, seeing people who like Fidel Castro warn about a Trump dictatorship makes me unsure if I ought to laugh or cringe.
Seriously, there is no chance of a dictatorship unless a full-scale civil war breaks out, which we all know isn't going to happen, and even then it would be highly unlikely. The National guard and police may have to crush a riot or two, but that's the extent of it.
as we all know, every president/congress/etc thus far has followed the constitution unerringly *nods*
