This is an interesting question in light of Gaetz withdrawing. I've heard he is an option to replace Rubio in the Senate because Floridians apparently love the guy. Can you imagine the PIA he'll be to those that were raising the biggest stink if that happened?
Hadn't thought of that. Seems plausible. Senator Gaetz.
Someone in the news said Gaetz could also resume his seat in the House next January. The logic was that he resigned from this session, but since he was reelected, he can just show up and be sworn in in January. He's still the Rep-elect for the next session.
As for Rubio, I can't help but wonder if Trump isn't just setting him up for a fall. Once Rubio is settled in, and no longer safely in the Senate, Trump will kick hi to the curb. Payback for impugning his manhood back in the debates. I don't usually think of Trump as playing the long game, but he is known to hold a grudge.
