The GOP doesn't have a plan. The factions within the GOP may have one. If this election has taught us anything, it's that unlike the majority of the Democratic Party, the GOP is not on the same page. There's a reason that a populist will never succeed in the Democratic Party and it's just how much the DNC has control over their own primaries. The one time they failed was in 2018 with the Justice Dems, but since then the Democrats have absolutely clamped down on any more populist socialists that have been trying to rise up with the support of Sanders or AOC.
The neocons are probably not going to return. The reason for it is that they've simply realized just how better it is to cozy up with the Democrats than it is to do so with the Republicans. Biden is probably going to start a few more conflicts in his term and they're not going to have to deal with anti-war rallies like they had to during the Bush era. Lincoln Project isn't trying to wrestle back in with the GOP, they're trying to grift the Democrats for more money and positions. They know how hated they are by the majority of the Republican base right now. Some, like Crenshaw, might find success, but I don't think he'll do so well in presidential primaries now that the voters are going to be coming out for traitor's blood.
The RINOs unfortunately will remain in control of the party, but the RNC isn't as powerful as the DNC. RIght now, the RINOs are going to go into the defensive. Without the Trump movement, the party is screwed. The Georgia GOP is going to get absolutely demolished in the runoffs. Perdue and Loeflerr should just concede now and save us all the trouble. Arizona seems to be going in a similar direction, but there's more hope for them thanks to having people like Kelli Ward and Paul Gosar that are currently sharpening their knives and waiting for the opportune moment to strike against Ducey's cuckolded ass. RINOs are proud, professional losers, plain and simple, and their base doesn't like losers.
Several populists will try to take control of the party in 2024, and my prediction is that they will win the nomination, more than likely Cruz or another MAGA figure like DeSantis. Unfortunately, they will lose against Biden or Kamala.
@Secret Asshole has repeatedly been correct in saying that the reason Trump lost is because he didn't have a machine in the ground like the Democrats had. He didn't have people to confront the 4AM magical ballots, no boots to help when the poll watchers were turned away, no authorities to give him evidence of election fraud. He didn't do anything even when he knew that the media would be against him, Silicon Valley was against him, social media was against him, the fucking US postal service was against him, and the payment processors were against him. He did nothing despite the 2018 AZ Senate being fishy as hell and essentially the groundwork for how to do election fraud and it came to bite him in the ass. This is going to be a painful lesson that the GOP will have to learn. They can't win until they create a machine of their own.
