Point of view as an outsider on duopoly:

US used to be predictable. Dems or Reps, they had their own way of doing things and you could plan your life accordingly (whether we want it or not, US politics affect us outside US).

With Trump, it feels like 3rd party is created and it replaced Reps. You can't count or trust on anything anyone from this new establishment says or said at any time in the past. Things change from minute to minute. One day is white, another day is black. Most blatant lies are at random accepted as a truths and long standing truths are called lies.

It’s like someone you knew for a long time, someone you could argue with and still understand, suddenly became unrecognizable. The rules changed, consistency vanished, and even basic shared facts are no longer agreed on. From the outside, it feels like dealing with someone who suffered a personality-altering brain injury the same name, the same history, but none of the old predictability or shared reality.

I don't know how it happened or why it happened, is this real state of Republicans or US or is it just a fluke, is it good for US or bad in long run (i have my doubts which are not topic of this post) but it's wild to see from outside.
