Marco Rubio Wins Primary in Puerto Rico GOP candidate is apparently aiming for Florida victory By Neal Colgrass, Newser Staff Posted Mar 6, 2016 5:09 PM CST 37 comments Comments Republican presidential candidate, Sen. Marco Rubio, R-Fla., shakes hands at a rally in Toa Baja, Puerto Rico, Saturday, March 5, 2016. (AP Photo/Paul Sancya) (Newser) – Marco Rubio is dominating the Republican primary in Puerto Rico on Sunday and will likely grab all of the island territory's 23 delegates, Politico reports. With nearly half of precincts reporting, Rubio had 71% and second-place Donald Trump only 12%. Rubio just needs 50% to take all of Puerto Rico's delegates to the Republican convention, CNN notes. Rubio, who has only won Minnesota so far, likely has to win his home state of Florida to stay in the race—and may have targeted Puerto Rico with a visit Saturday because Florida has a sizeable Puerto Rican population. Tens of thousands of people have moved from Puerto Rico to central Florida over the past few years seeking housing, jobs, and the chance to vote in the US general election, the Guardian reports.
