I wonder if a parliamentary system functions as something of a safeguard against this. In a parliamentary system, a hypothetical Trump party might have been able to get a sizable number of seats, but probably not an outright majority (since many of the people who voted for him hated his guts, they just didn't think they had a better alternative), so he wouldn't be able to control the government without forming a coalition with another party that could act as a moderating influence.
