I’d call it a “flawed democracy.” The ideals behind it were sound, but the execution left much to be improved upon. And we’ve made many improvements (though we still have a ways to go).
Still, even a flawed democracy is preferable to Dictator Trump.
One big lesson from Trump’s presidency was that many of the rules we thought constrained politicians were only “Gentlemen’s Agreements.” They held up because everyone agreed to abide by them. When Trump walked in, refused to abide by them, and wasn’t immediately struck by the political equivalent to lightning from heaven, all the politicians on the right decided that they could toss those pesky rules aside also.
