Answer:
Because he is a national meme
Step-by-step explanation:
We can still debate whether or not Bernie Sanders would have won the 2016 presidential race had he, and not Hillary Clinton, been the Democratic nominee. But there should be no debate about 2020.
No, Sanders wouldn’t have won. Elizabeth Warren wouldn’t have won either. And while it is less clear how moderates like Amy Klobuchar or Pete Buttigieg would have ended up, there are strong reasons to believe they wouldn’t have won either.
Give Democrats, generally, some credit here. In every single poll they said the number one criteria of their 2020 presidential candidate was someone who could beat Trump. Eventually they decided this candidate was Biden. Turns out they chose correctly. And given the tight nature of the election, it is possible that of the 27 Democrats who ran for the presidency, Biden may have been the only one who could have won it.
