I do think his base was left but we're talking the extreme left like people who support people like Nina Turner. Tesla is literally a cult. I went on some forums and they talk about Elon Musk being the best thing to humanity and he is saving humanity. I am not being hyperbolic. Those are actual words from Tesla supporters.
Another thing that was so odd was when people would bring up Tesla's abysmal build quality, it would always turn into a flex about their stock. They just keep believing the lie. They're convinced the Cybertruck is going to put Ford out of business even though the Cybertruck doesn't exist and keeps getting delayed until next year. Tesla's are just junk. They have the worst reliability rating, are poorly engineered, have massive body gaps, and colors don't even match and yet Tesla owners give him a pass. No way GM or Ford gets away with that. This was all before Elon Musk bought Twitter and showed his true self.
