If that's all they will do (vote democrat), it's still better than them being chuds. If they, however, use the fact that he namedrops Lenin to go further, that's also a good thing. Also, I don't think his readings are "lies" they're just readings! It's like saying you are Martin Luther and have the correct interpretation of scripture. Lenin's works are a text, and while there's doctrinaire readings, perhaps he's flexing the truth to get people to approach the works.
I don't buy that they were "heading left" necessarily either - what's that even mean? Is it abstaining because accelerationism is the best principle? Unless "heading left" is joining a union, building the organization, and creating strike power, I literally don't know what you're talking about here (and that's not mutually exclusive with voting for democrats).
is obviously a very minor thing, and he's doing work to platform progressive candidates, but if "heading left" is just voting for the most communist candidate - most people who he gets in would have never done that anyway! Meanwhile, when he emphasizes unions, organizing, and building actual power, he's actually moving people left.
