The biggest current problem for this next generation is the failure to get beyond Trump’s populist success in selling anger and grievance to excite online donations and right-wing talk shows.
GOP primary voters told a CBS poll last month that their top priority in a presidential candidate is someone to “challenge woke ideas,” among Democrats. An unnamed candidate who makes “liberals angry,” was not far behind with 57 percent support.
This feel like the sort of "<insert party> in disarray" articles which come out every few years. The last time these were rolling out about the GOP, they landed on Trump. While it's difficult to see what lies beyond Trump, I wouldn't doubt that there will be someone there to pick up the top hat and lead the circus. A quick look at recent history shows that voters are wiling to forgive just about anything. Nixon left office in disgrace in 1974. Regan was elected in 1981, winning the national popular vote by 9.7%. And even with the complete clusterfuck which was Trump's Presidency, Biden only won the National Popular Vote by 4.5% and because of the Electoral College map, nearly still lost.
While it may not be easy to see whom the GOP will pivot to next, I have little doubt that they will find someone. Maybe it's DeSantis, maybe it's someone else. But, the US electorate has shown a willingness to keep going back to the GOP every few years.
It's usually the Democrats are in chaos! The difference here is that the GOP actually is divided due to the 'Freedom Caucus' causing a Civil War in the GOP. Traditionally this leads to a fracture, a third party, and a decline in power. See the Whig Party for examples.
The dream scenario is the gop fracture kills off the republican party and the Democratic party splits in classic conservative democratic part and 'radical' left democratic party to fill the void.
