His lawyers have claimed Trump would willingly surrender himself in the event of an indictment. His lawyers have claimed all kinds of things.
The most interesting thing would be if Trump doesn't submit willingly and DeSantis finds himself on the hook to extradite Trump to New York.
But yeah I think Trump just won the primary and lost the general.
These charges are child's play compared to what he could/should be facing from Fanni Willis and Jack Smith. But it does help break the seal, so to speak, on indicting a former president. Still, he won't see the inside of a prison cell this side of the 2024 election no matter what happens from here.
