Well, that certainly hasn't happened in my lifetime. Are you sure democracy is actually working at all? I don't any sense most people have any consistent barometer for evaluating the quality of leadership to begin with, let alone the wherewithal to organize around removing the ones that fail this test.

It happened to Joe Biden. He wasn't swapped out until it was clear he would lose the popular election.

Objectively, he was the most effective US president we’ve had in decades.

Trump’s campaign promises were all of the form “X is so bad it will destroy the country and I will fix X”!

Replace X with some problem that Biden had already fixed (factory investment, crime rate reduction, getting inflation under control after the previous president printed money for 4 yeara, etc, etc).
