It could be worse though – in a more polarized environment, Tucker Carlson would feel unable to invite someone anti-Trump on to his show, even to talk about some topic unrelated to Trump. It is interesting to contemplate, that no matter how bad America's political polarization has become, it could be worse.

Actually I do wonder whether centre-left media outlets have the same freedom that Carlson has, to platform dissenters to talk about matters unrelated to their dissent.
