2024 will either be Pence or a loyalist to Trump like Tom Cotton. Republicans lose this election - Biden is either re-elected or his VP is elected.
2028 will be more of a Mitt Romney type - a governor from the northeast who is too moderate for the remaining Trumpists in the party, but too right wing for a lot of independents. Biden's VP is elected or re-elected - the Republicans lose a third consecutive election.
2032 will be a moderate who wins as Trump's influence on the party finally wanes.
Something like this. And perhaps the Dems go all out with AOC and Omar by 2032 and it produces something like 1992 where new trends begin.
