@Vee I was reading about that earlier. Politico, which I haven't read much in a few years for obvious reasons, claims that Rick Scott had already been planning to run a leader campaign, to the point of recording a video.

Scott is a ghoulish figure - the clip of him bragging about making unemployment benefits impossible for Floridians and the extremists he was speaking to briefly being too ashamed to applaud still chills me when I think about it - but he clearly knows now is the time to act, as the map means Republicans stand a very good chance in the Senate. He can take over, do what he does best (go on TV and talk about hurting poor people), and then just wait to become Majority Leader.
And of course faded media darlings and chinless wonders who know their national ambitions are gone or will soon be gone are happy to join him.
McConnell is vastly overrated by a media that sees all Republicans as geniuses and right in step with the public at every turn, but other than some blunders he made in the runup to the Georgia runoffs in 2021, he generally has much stronger political instincts than most of those around him. If Scott gets more power and Trump's picks continue to hold sway in the party - and wretched Peter Thiel, of course (I imagine he's the one who put Blake Masters' perpetually traumatized Toy Story bully face on national television last night), that may be the best chance Democrats have to hold on to the Senate in 2024.
