Many states have both. I'm actually surprised it's not all states.

Those that do both typically have some state law about the elected delegates at the caucus being bound to vote for the candidate who received xx% majority vote in the primary, but can break that vote if that majority is not met, or if there is a recast at the convention because there was no clear victory. (Some states do not require delegates to pledge their votes).

In 2012, Ron Paul actually had a better chance at the nomination than most realize because Paul supporters dominated the caucuses even in states where Romney was the clear victor in the primary. If there was a recast at the convention that year for any reason, I'm fairly certain Ron Paul would have won the nomination in a massive upset.

I suspect DeSantis supports may try the same tactic, so be sure to attend your local caucuses!
