Plus the Governor over there is Republican, so any real complaints about it giving Dems a leg up are rather moot. We all know Trump is desperate for some sort of positive achievement to, well, trumpet, about, this one is dropping straight into his lap free of charge and with little effort needed on his part, so, why
wouldn't he jump at such a chance.
They actually did vote for it last time, but there were lots of problems with the ballots or something, so, Congress just sort of let it slide. So, hopefully there aren't any of those problems that they had last time.
The only thing remotely controversial about it are their economic problems, but they aren't the first proto-state to have economic issues before becoming a state. Didn't Texas have a whole bunch of economic issues during their brief stint as a sovereign nation (the only other states with such distinction are Hawaii because Kingdom of Hawaii, and possibly California in a brief period while waiting for statehood)?
I'unno, and I don't recall at the moment 'cause applicable populations basically aren't where I live, but I think a question that might decide how the GOP in particular (given attempts to court the cuban/etc. vote in recent years), but both parties to a degree, would jump, is "How do minority populations in florida feel about PR statehood". Maybe another state or two that's potentially effected and not, y'know, New York.
BTW, there are a LOT of Puerto Ricans in Florida who moved to the state to escape the economic problems.
The whole proccess of new statehood will be fascinating for everybody since it's been roughly two generations since a territory became a fully fledged state.
