Loads of podcasters/commentators drift further to the more extreme right. It's a self perpetuating process, by being more extreme they get more views, get more praise from that viewer base, growth their profile and income, and so they play into it further and further, usually with a level of self-deception mixed with outright grifting. Disappointed with Russell, he had no need for a small increase in his viewership or income as he's already financially set and had the necessary status to not need to pander. I wonder whether he genuinely believes in his new narrative and has come to that conclusion independently, or if he's shifted his narrative because he's networking/making deals with certain lobbyists/financiers/powerful people. A lot of the right wing podcasters give the impression that they're independent but they're backed by billionaires or groups with political agendas. You can see why he'd be a great political tool to use given his status and flamboyant verbosity.
I hope that in time he will shift back towards the centre or left, and bring with him some of the right wing crowd to a more centrist or left wing position.
