A massive problem in the US is that the completely broken two-party system has essentially killed the political spectrum. People more-or-less vote against the party they dislike more, not for the party they want. To see any form of change you need someone like Trump to completely take over a party in one go and kill the old one from inside.

From an outside perspective the US does not have a political left. The policies proposed by the Democrats are roughly in line with the mainstream right-wing parties in the rest of the world. A mainstream left-wing party would look an awful lot like someone like Bernie Sanders - and we all know the Democrats would rather platform a wet paper towel and lose than see him gain any kind of power!
