I think it's worse than that. I think it lacks moral clarity because I feel like he hates Jewish people so he has no morals. In your example, ask yourself if you'd give such benefit of the doubt to someone who wouldn't condemn someone for using the "N" word. I don't think you'd vote for someone like that or lay any cover fire for them.
But at the end of the day, this guy is likely going to win. We are going to see what happens. But I believe much like Lori Lightfoot failing in Chicago brought about Brandon Johnson who has failed even worse, the left will only find another elite, capitalist (gasp), white person, wealthy person, oligarch, or someone to blame when this guy fails too. It's what happens as their society and city falls apart around them because the ideology doesn't work, it can only find another oppressor to blame. And usually that blame is shifted to the very system that has made Western Civilization so great that people want to escape other cultures and societies to move here.
