I don't watch Fox News, and don't know a lot about Tucker Carlson, although I've seen some bits of his broadcasts occasionally.
Is the argument that he really says one thing in public, but privately says the opposite?
For example, does he say in public that the election was stolen, but in private says it was not?
I watched the whole video presented in the OP and didn't think the attempts to psychoanalyze him amounted to much. But at the end, the argument that he says one thing publically and the opposite privately, should be definitive, without the attempts to explain why. But it wasn't clear to me what those things were. Maybe it's obvious to people who watch him regularly, but I don't.
I'm talking about outright lies here. Obviously, any 'public person' will shape what he/she says for his audience. This is clearly true of politicians, and of TV journalists. In fact, everyone does it. If we didn't, we'd live in a LIAR, LIAR world.
It's the outright lies I'm asking about.
