It is very likely that Trump will not be able to vote for himself on November 5, 2024. No photo op of a politician voting for himself.
While it's not clear if Judge Merchan will actually give Trump actual prison time, and a lot of legal experts do expect home confinement or probation. They are all over the place on when any of these sentences would actually become active, some thinking at least after Nov. 5.
If so, Trump will not be able to vote for himself under FL law. Current FL law does restore voting rights of felons, but only after they have satisfied all aspects of their sentence, be in prison time, probation, or even paying fines.
