Do you need a passport to go to Guam? If you do, then it's comparing apples to oranges. You DO NOT need one to get into PR. And even if you don't need one for Guam, then you're way off base anyway. And your ignorance is showing. Puerto Ricans CAN vote in Presidential elections if they happen to have an address in the States. And once again, thanks for nothing. Next time maybe you'll see the forest for the trees.
