One thing I try to point out is complicated outcomes usually don't have a single cause. There isn't precisely one reason Dems did better than all the highly paid politics knowers thought. I am not going to claim it is because they finally took my advice and embraced full communism.
I don't even have strong opinions on what they did right. My take is more that maybe people don't love it all that much when Republicans are assholes, and they haven't tried much else lately.
