Overthrow them and replace them with who? Who should be the leaders of the United States? I am open to ideas for who to vote for, and I think a lot of people are. That's why someone as obviously ill-suited for the job as Trump did win -- people are so desperate for something different but don't really know what they're looking for.
There's 300 million plus people in the United States. Sure, we could overthrow the government, but you can't just go "my way or the highway" with policies; you'll never get support doing that. As spoonjim said, Trump wasn't elected for no reason; He was elected because 62 million plus people voted for him. And with this past election, that number went up to 74 million. And the opposition (Biden/Harris) got 81 million. For comparison, George Washington's support was almost unanimous. Sure, it's not exactly the same, but Washington had the support he did because everyone believed in a common "enemy", the British Empire. Today, depending on who you ask, the enemy is either "the Demonrats" or "the Trumpanzees".[a]
Not to mention that the United States itself wasn't formed overnight; it was the product of many compromises. There's even a whole Broadway play about it: Hamilton[b].
[a]: Yes, these are actual "names" I've read online.
[b]: Sure, it's exaggerated, but it's pretty accurate
>the enemy is either "the Demonrats" or "the Trumpanzees".
You forgot Muslims, Mexicans, poor people and the non-white people of the US. They are just as much an enemy as the opposing political party (and the Russians and the Chinese....)
