There isn’t anyone in American public life who is truly popular across the board anymore. The only one who even has close to a healthy majority is Chief Justice John Roberts and that’s no doubt because nobody ever hears from him.
Naturally, it’s all very partisan.
I guess Joe Biden is so unpopular with Republicans that Gallup didn’t even bother to include him on that second list.
Notable that Donald Trump is not on this list. He’s certainly more of a political leader than Jerome Powell, whether he currently holds office or not.
