As a non US citizen,I would say US politics is not all that bad, neither party can be overthrown or something.
I have plenty American friends who live or used to live in various states and different segments of society. Like anywhere else it's not perfect, but top 5 in the world I would say.
In many latin American countries there is a fierce divide between left and right, the distribution of wealth is unlike anywhere else, the poor live in favelas, the middle class lives in gated and secured communities, simple things like leaving a gated community can be a danger to your wallet or life.
The leftists are very extreme, the middle class is conservative, they want their status protected. Neither side realizes that it's better anywhere else in the world, almost literally.
The left does not even offer a social system for the unemployed, this cannot deserves the label left and leads to most of the crime, they happen due to dire economic straits.
No really, the USA are doing fine.
Some people say the left in the us is a right wing light, but that is not accurate. Some states are as left as many EU countries.
If you think either Obama or Trump were the worst, don't worry , Europe has worse, in the UK, Farrage, the hypocrite, Boris fake name Johnson and many more.
