No, they're not stupid. But they still don't care about the threat he poses as long as they get their ratings. The man is an authoritarian and incited an armed insurrection and he has not given up. He wants that power back and broadcasts are his only form of communicating with his base, at the moment. So, if you want to protect democracy and want him to become irrelevant, you do not give him a stage where he can broadcast his lies and propaganda. Ever.They're not stupid.
