Registered members of each party only voted in their party's primary, while voters who were unaffiliated chose any one primary in which to vote. There were 60 Democratic delegates[1] and 23 Republican delegates[2] to be allocated.

Twelve candidates appeared on the Republican presidential primary ballot, with only four still possessing active campaigns:[4]Marco Rubio, Donald Trump, Ted Cruz, and John Kasich
Sen. Marco Rubio carried the primary with 73.8% of the vote and was awarded all 23 delegates due to the territory's 50% winner-take-all threshold.[4]
