I mean, the US rallied behind Trump, if anything.
Democrats in particular didn't go for somebody from the progressive wing, but I'm not sure if that would have helped. Look at Jeremy Corbyn. The actual alternative would be for party leadership to recognise the system was done for and aggressively manage it's collapse, but they didn't come anywhere close to that. The class of people in charge seemed to prefer the theory that they could manifest a functional democracy by believing in it hard enough.
Maybe there was another path if you change things all the way back in the 'oughts. By Obama's presidency things were already in a deadlock death spiral.
