Agree. I think this is Trump's power play. He wants to be sure any wavering Pubs in the House and Senate are brought back in line. Gaetz serves both purposes. He's generally despised in the House, including by his fellow Pubs, but this move moots the pending House report on his conduct, which was almost certain to be brutal. And if the Senate balks, Trump will just get him in through a recess appointment, showing the Murkowskis and Collinses of the world they don't really have any power to stop him. The lesson to everyone is that if you're loyal to Trump, it doesn't matter what terrible things you do. He'll take care of you, even if that means bypassing checks and balances to give you a special favor.
We'll see what happens but I think it's highly likely Gaetz is our attorney general by this coming February, and what a clusterfuck that will be.
