For people out of the loop, GOP Iowa Caucuses for 2024 are already in which gives primary delegate declarations to the candidates they support. Donald Trump won the state with 51% giving him 20 Delegates.
The total delegates are:
Trump 20
De Santis 9
Haley 8
Ramaswamy 3
This seems like a lot but also Trump is off the ballots for at least 2 states so it's possible for him to lose the Republican Primary.
