Question: do puerto rico vote for u s presidents

Answer: No, Like other territories, Puerto Rico can participate in the presidential primary process. It holds a primary election in the spring of each presidential election year. Then the parties choose delegates to the Republican and Democratic National Convention, who are pledged to vote at that convention for the winners of Puerto Rico's primary, but that's the end of their participation in the presidential election. See United States presidential primaries in Puerto Rico, 2016.
