Puerto Ricans (and Guamanians) can’t vote in US elections for Pres, Senate and Voting House members. They do have, by grace, non-voting members of the house, and the political parties (Both R and D, for 60+ years) give them small representation at party conventions. But they don’t have real voting rights, as they are not constituents of any of the United STATES
Thank you for the correction, BohDaThone. They can vote in the primaries only, not in the actual election. My memory failed me (as per usual). I recalled seeing their flags on the Republican National Convention floor once upon a time.
