I had the same thought. When Democrats run a likable, popular candidate they win. Bill Clinton, Obama being the two most recent examples. Trump won largely because his brash, crude, swaggering demeanor appeals to a lot of people and Harris was a candidate that was defaulted in because Biden was just out of gas; nobody really wanted her. Not saying that the Democrats should look for someone like Trump but first and foremost they need someone that a lot of people find likable.
