Populism from the left gets just as much traction from the working class as populism from the right. Centrists doing poorly has nothing to do with leftists. People liked that Trump was extreme and anti establishment and were very clear about that. He beat a Bush in the primaries. It was Jeb, but still. People liked that he was “telling it like it is”, which a centrist never will. Additionally, leftists politicians consistently come across as more genuine, even to republicans, which goes a long way. When Harris says she cares, I have no doubt that what she cares about is her career because it’s so transparent. Leftists stand for something and that encourages trust and interest and support. If they had centrist dem backing the way magats had centrist republican backing, this country would have gay space communism already.
