You know in regards to foreign policy of US it is happening for long time, at least since 90’s. What Trump does right now just makes this stuff really obvious for ordinary people.

From my point of view as a foreigner the US political system is broken and nobody tried to correct it so this was only matter of time. And yes when something like this happens most people just want to get by.
If you look at it from the political side that this is the basic idea of liberal democracy.
Everyone votes in their best interest and especially in proportional representation you get some compromise of the interests.
Right now at least in politics people act less in their own interest but more of what they emotionally feel like their interest.
