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.
Except they never have. The referendum was carefully arranged to make it look like they did, but they didn't. They were asked two questions, the first being, do they want some change in their status and the second being if the status was going to be changed, which status do you want it to be changed to. Yeah, a majority answered they wanted a change and a majority answered that if there was a change they would want it to be to statehood, but that does not mean that if presented with a straight up and down vote on whether they want statehood or to keep things as they are, that statehood would win.
That is why 2020 is the earliest we'll see Puerto Rico voting in a Presidential election. There will need to be such a straight up and down vote before Congress will ever consider offering Puerto Rico statehood. The soonest I see a 51st star being added to the flag is 4 July 2019, after a 2014 straight referendum on statehood, a 2016 election for a convention to draft a state constitution, and a 2018 vote to adopt the constitution. (And at the same time hold elections for 2 Senators and 5 Representatives who would take office if the constitution were adopted. Puerto Rico would gain a Class 1 Senate seat which would be elected to a full term in 2018 and a Class 2 Senate seat which would be elected to a two year term in 2018. Incidentally, if they follow precedent, then in the first election, Puerto Rico will be voting for a Seat A and a Seat B and which is which class would be determined by lot when the new Senators are sworn in.)
