Except, you know, Biden has already decided to run, so it will be Biden vs Trump 2.0.
That seems to have slipped Styx's news feed, it seems.
Short of Biden dropping dead, he's the Dem candidate for 2024.
Biden has claimed he's going to run, yes. That in no way means he's actually going to, or that if he does run, that he'll make through the primaries.
DeSantis holds to his "florida 1st, POTUS in 2028"
DeSantis never said anything of the sort.
the Uniparty
This is why I don't take claims about "the uniparty" seriously, given that the people using it don't seem to understand it. In the context of Trump getting sabotaged and prevented from winning the republican primary, that would be due entirely to the actions of the republican party and the republican party alone. They control thier own primaries, it's not a joint thing between them and the dems where "the uniparty" could sabotage them.
