Will it? Are you sure? US media is now so polarised that the various echo-chambers almost never intersect. The US right anti-covid train has been going for an appallingly long time, why would it stop now due to mere facts. There have been facts all long, that hasn't made a difference. To that topic or others that I could name.

Are you sure that there isn't? Have you looked? I linked to an article "debunking" the same character, upthread. I know their name and their position, but I do not follow all their antics: Circus clowns gonna circus clown. It's not on me to research a debunking of that specific performance.
