For an example of Lewis said, Puerto Rico has its own Olympic team now. That'd change after statehood of course.
But what does that matter? You and Lewis seem to be insisting that they'd have reservations about statehood
despite voting for it. If they valued their independence so much, they would have voted for independence, and that would have been fine. But they voted one way, and there's no use in going on about a minority that goes the other way.
Not everybody in Hawaii is entirely happy with statehood, either.
And how much is "not everybody"? Are the Filipinos and Japanese, the two largest ethnic groups in the state, part of "not everybody? We may take the step of assuming that Native Hawaiians might "want their country back" but the fact is that they constituted barely one in ten of Hawaiians, and chances are most of them enjoy being Americans.
Considering that Puerto Rico made the odd choice of voting for statehood and yet voting for an anti-statehood governor, it's highly improbable that the government would make any formal move to apply. If statehood is to occur, what will probably have to happen is that another referendum will need to be held in 2016 and get a majority, plus a PPP governor will need to be elected, then I think that Puerto Rico can be granted statehood no later than 2020.
