I've noticed that a lot of these people will lean left for a minute, because they hope that it will get them a get out of jail free card for being problematic in specific ways.
They find out quickly that the left doesn't do that. I can support your stance on XYZ while still disliking you and not wanting to do business with you because of ABC.
So then they switch to regressive stances, because those people will cheer you on for being awful.
Same thing happened to Reagan. He created the EPA as an executive agency to avoid Congress creating and empowering an independent entity that the executive wouldn't be able to control. He thought it would get him votes from the left. It did not, and he pretty much immediately stated that he regretted it because lefties didn't buy his bs.
