> But they didn't end democracy because they couldn't, because our Federal government has a system of checks and balances that limit the power of the president.
Checks like Congress, a majority of which is terrified to stand up to him even after an attempted coup and comically bad cabinet appointments?
Or the courts, many of whose judges he appointed and shamelessly render verdicts (often on his behalf) without recusing themselves over conflicts of interest?
Or the executive branch, of which he is the head, and can cycle department heads like an episode of The Apprentice?
> He was president once, and was not able to pull off a successful insurrection, or murder any political opponents
The US passed an entire amendment to its constitution to prevent insurrectionists from repeated attempts to take over. The fact that he attempted to do so is already treason. One doesn't have to succeed to be disqualified. Otherwise what's the point of the amendment? Just keep trying until you succeed.
Yes exactly those checks.
Even if your characterization of the independence of the three branches of government is valid, the circumstances are far from unique in history.
In the past, there was always a threat that if a president got out of line, he could be impeached. But the impeachment clause has been rendered inoperable by Republicans.
The first time Democrats tried to impeach Trump, Trump argued in front of the Senate that he's allowed to commit crimes, including extorting bribes, as long as he does it for the good of the country. On that basis, the Senate acquitted him. So now the the standard set by Republicans is that even in the case of extortion and bribery, the president should not be removed from office as long as he had a patriotic heart.
Worse than that, the Supreme Court affirmed that the president has sweeping executive immunity, making any prosecution of an impeachment case impossible; the Executive controls all of the information Congress would need to prosecute the impeachment, and as we saw during Impeachment I, Trump is fine to just flout congressional subpoenas. Furthermore with the new doctrine of Presidential Immunity there is no judicial recourse for them to compel production of the documents they would need to prove an impeachment case.
Finally, we further know impeachment is impossible because when they tried it, Trump argued the correct recourse was the courts. But when we tried the courts, Trump argued the correct recourse was impeachment. That cannot be the case in a functioning system.
