> the democrats put forward a checkbox-ticking uninspired candidate that had no business running for president
So you're saying the playfield was even. And the man still won.
You might consider the field even for other reasons (which would make your comment something of a non-sequitur), but those adjectives certainly do not apply to Trump, regardless of what you think of the man and his politics. Trump very famously did not tick GOP checkboxes, and he has inspired a cultish following in a way that Clinton/Biden/Harris clearly cannot.
Bernie is the closer analog to Trump in the Democratic Party, at least for this comparison. Trump is not a checkbox filling candidate by any measure. He was the protest vote against the system.
