Considering that as soon as Congress Gets their heads out of their collective Asses, and the Anti-Castro Old guard in Miami become too senile to care that embargo will be gone and Cuba will be an Economic Vassal of the United States Yet again within 5 years.
If they're Smart They'll want a real say in US policy and the Only ways to do that are to either hold the US by the (Economic) Balls, something they can't do, or become a State. With a Population of ~12 Million Cuba should have 18-19 seats in the House and 20-21 Electoral Votes they'd have serious weight to throw around, same if they tend to work in concert with Puerto Rico(likely #51) and Florida. If they were a state they'd also have a better deal for Sugarcane growing because of the Tariff, especially if the sugarcane growing states can outmatch the Midwest and get the Corn subsidy reduced, or get a ban on the use of HFCS. It'd actually be something of a Sweetheart Deal or windfall for them, and us because the US would now have the Best Doctors on Earth(Seriously), they'd probably keep their Health Care Program instead of adopting the Current system, but that's just fine.
