as Puerto Rico is equal to MA
Puerto Rico is not "equal" to MA. At present, there are no Rep or Dem organizations in the country, so any prediction is difficult, since the local party system would change after statehood. However, at present there are two major parties of similar strength on the island, and it is not unlikely that one of them would become the basis for the local Republican Party organization (given that one of the two parties is already affiliated to national Dems, this becomes even more likely). Now, this might be a very peculiar Republican organization, dissident within the national party on many issues, but it would still be a Republican Party, and it would be a locally important force. A moderate and/or Hispanic Republican candidate would have a good chance of winning PR in a presidential election. I don't believe MA could be, at present, competitive, given almost any realistic Republican candidate.
Given that the New Progressive Party once *was* the state's Republican Party, and split away for some pretty good reasons... it's sort of unlikely they'd go back to that, or at least that many of their voters would follow them there.
Although... given the remaining strength at the nonfederal level of Republicans in Southern New England ... I could imagine PR having a competitive state New Progressives sort-of-affiliated with the Republican, and a Popular Democrat lock on congressional representation. I could *imagine* it - but competitive congressional elections, and PDs and NPs then both caucussing with the Dems, sounds more likely.
