My family that are anti-Biden/anti-Dems are not talking about Trump at all, but Desantis is the one they bring up to be the next president in 2024. They also have bought into the demonization of Harris. Harris will be a loser, if Biden does not seek re-election, and the Dems try to run her in 2024. She actually has a lower approval rating than Biden. The Dems need another Obama or Bill Clinton to come forward, especially if inflation continues to be high or the economy tanks, if they want to win in 2024 IMO. The primary candidates from 2020 just do not have anyone that can overcome bad inflation or a bad economy. If they had the charisma to pull it off, they would have trounced Biden, and be president now.
Trump doesn't run. The RNC will pay Trump so much money and prop him up as the Godfather meets Wizard of Oz backroom dealmaker that MADE Desantis. Trump will get everything he wants (money, influence, and the appearance of power) with none of the bothersome work that goes into being rich, influential, and powerful.
I think, if Trump loses the nomination, they just need to have DeSantis, or whomever wins it, tell him they will pardon him, if elected. If he tries to burn the GOP down, and they are elected, no pardon for the Trumps and they will "encourage" prosecution for any crimes he was involved with. They can pardon or give immunity to any co-conspirators to fuck Trump only.
Only problem is Trump is an old dude with mental instability so he might just try to burn it down anyway.
