No, it's lacking political savvy. Puerto Ricans in the US proper would still vote predominantly for Obama, as they are largely addicted to Democrats. And Mexican Americans (by far the largest "Hispanic" subgroup) and other voters of Latin American origin would likely not identify with a Puerto Rican candidate as countryman in any sense. Can't escape the feeling that the posted article from "The Hill" is bogus and that Fortuno's name could be thrown out here by Democrat sources merely as a trap to mislead Romney's camp.
People also need to look at the issues that have arisen due to the re issuance of birth certificates there. Its been a mess.
Maybe he should put a genuine Republican on the ticket just so it’ll be balanced.
