These are people too and they should be able to have a voice. They are tax payers and citizens just like the next man. Regardless of peoples status if they are legal citizens then I do not feel that they should be deprived of the great opportunity to make change.
No, residents of unincorporated U.S. territories should not have voting rights, because they have different interests than those of United States citizens. The United States should listen to their opinions and help with problems they have, but at the same time, if they want to have full voting privileges, they need to incorporate and pay taxes.
