Bernie is a bastard, but I think it's backwards thinking to blame voters rather than candidates. In a nominal democracy, it's the job of the candidates to appeal to people to get votes. If there is any merit to this idea, we must conclude that the failure was the Harris campaign for not generating the confidence needed to vote for her -- which is a very expected outcome when you're running as reactionary a campaign as she did, calling the wall a "good idea" and so on.
