Would Americans want Puerto Rico to be state however? I think there has been little discussion what this would actually mean, in practice, if it were to happen except for Rick Santorum, who basically gave reasons why I doubt most Americans would support statehood for PR if it actually came to it.
If PR were to ask for statehood, it would be extremely difficult politically to deny it. It would, in fact, require taking an outright anti-Hispanic stand, with little possibility of any sort of a fudge - not something one would necessarily want to do.
It is further complicated by the fact that within PR it is the relatively pro-Republican PNP that's pro-statehood, while the outright pro-Democratic PDP prefers the status quo. While PNP is not exactly the local affiliate of the Republican party (it does have a pro-Dem wing, though that one is relatively weak right now), nearly all the local Republicans are part of it. If the national Republican party opposes statehood, it would amount to a complete destruction of the local Republican organization on the island. As Puerto Ricans are US citizens (something that, in the short term is not even possible to change if PR declares independence), they can and do vote when they find themselves living on the mainland. Oposing statehood would, basically, tell those of them who still vote Republican that their party does not want their vote - in those many words and, once again, without much realistic possibility of a fudge.
It would even be pretty hard to make a principled anti-statehood argument in a way that wouldn't alienate at least some normally pro-Republican Cuban-Americans: it wouldll all come down to the issues of language and culture that Cubans themselves hold dear, and the arguments would undoubtedly degenerate into outright anti-Hispanic claims that would make a lot of people feel very unwelcome in that sort of a party. At that point, being a Hispanic (even Cuban) Republican would become a lot like being a gay Republican - not impossible, but not that easy or pleasant.
To sum up, if the Republican party openly opposes statehood, it would go a long way towards making sure that the Hispanic electorate converges to black levels of support for the Democrats. And, of course, when and if PR votes for statehood, Democrats themselves would have no incentive at all to oppose it. Hence, though a number of diehard anti-Hispanics can be counted on making a few passionate speaches, nobody who cares about national political implications would dare to do anything to prevent it happening.
