It’s entirely possible that democrats will try to hold together what’s left of the Republican Party after 2024. Let me state some points first: -Trump is a massive populist, he has created new issues for voters and completely skewed the stance of the party -Trump also has demanded loyalty from congress. He has people in power who are far far far more dedicated to him than the party -It is unlikely that whatever happens in 2024 will be uneventful. Be it jail, re-election, whatever.
That all being said, Bush was incompetent and this road is long but yes the republicans have been losing for awhile now. They are unpopular and have arguably lost the majority of the vote for 30 years. Their issues are failing them. Their leader is morally bankrupt.
Another big reason is demographics. Their demographics have been aged older and older with time. But instead of fluctuations or slow decline, we’re seeing massive unpopularity with younger crowds.
This makes it very hard to pivot. They don’t have many ways to appeal to young voters without losing their older base. They lost themselves entirely over trump in 2016 and in 2020. Senators who didn’t support trump lost their support. So it’s clear that a lot of the future of the party hinges on trump winning 2024. And I view that as unlikely.
