His family deaths and his own surgery give him a personal experience with the insurance issues that have probably driven this. I can see "the feds are good" and "I despise and want to kill health insurance CEOs" co-existing if you haven't read other theory. The main principle of his radicalisation is his lived experience, not books, so he has all the brain worms but the material conditions have still driven him to this.
So we know he was very much not a liberal (Jreg type of guy, every extreme at once) but it strikes me as a liberal thing to say. Checks and balances, maybe he likes that the feds track down corruption (lol)?
