Unfortunately yes.

Trump won during a time where incumbents lost by ~10 points. He narrowly beat a candidate that lost their only primary run by <2 point.

Trump's very vocal minority is very good at making people think there is a silent majority.

However, the democrats have been elected quite a lot this millennium and they've fully shown they're incapable of making necessary reforms so there's going to keep being populist candidates until there's new blue blood.
