No. He didn’t even win by any sort of thin margin.
The closest anyone even got to him was Dean Phillips got 19% in New Hampshire. I guess he spent his entire time campaigning there. Even state with the highest ‘uncommitted’ protest votes only got those up to 29.1%.
Some people here really don’t like it, but Biden was going to be the nominee. So I’m glad he ended up dropping out and it’s going to be Harris instead because it sure as hell wasn’t going to be Dean Phillips.
(I will say that if you include American Samoa in this, Jason Palmer got 56% of the vote.)
