We should keep PR, and get rid of NJ, and CA
I read not too long ago that CA is the 5th largest economy in the world. That's pretty impressive, considering it's a state in a country, as opposed to a country in and of itself(although i'm sure quite a few people might prefer the latter). Considering the diversity of it's contributions to the internal and especially the national/global economies, it probably has a lot more in common with a country competing in the world economy than a state. With that being said, it might be able to function on it's own, but I really do doubt it would ever happened.
CA does have a strong economy, but it also receives a good share of federal money. Not that it would, but a 'clean break' from the U.S. would significantly reduce its economic strength.
Puerto Rican will give you a slight advantage over being just "Hispanic", but only if you're a mainlander Puerto Rican (ie: from the States), not an islander Puerto Rican.At least this is according findings during the Grutter case.
