Isnt it true that Trump, arguably more than any person in memory, can start campaigning four years out from 2024, without having to make it formal, and therefore be bound by the laws surrounding someone that is formally running for President?

he can literally go anywhere he wants in the country, for however long he wants. Also, leading up to 2022 he can campaign alongside candidates that will go against Rinos, which will double as campaigning for himself as well.
