Marco Rubio romped to victory in Puerto Rico’s Republican presidential primary on Sunday, sweeping all of the island’s 23 delegates.

With all precincts reporting, Rubio was at 71 percent, well ahead of Donald Trump, who was a distant second with just 13 percent. That put Rubio easily over the majority of the vote needed for a winner-take-all delegate allocation.


Rubio was the only candidate to visit the U.S. territory, holding a rally in a San Juan suburb on Saturday. The Florida senator also secured endorsements from the territory’s three RNC committee members, Republican chairwoman Jenniffer González Colón, committeewoman Zori Fonalledas, and former Gov. Luis Fortuño.

The territory is ineligible to vote in the November general election, but both parties allow the island’s residents to participate in their respective nominating processes.

Rubio's victory provides him much-needed delegates in his quest for the GOP presidential nomination. In the four states that voted on Saturday — Kansas, Kentucky, Louisiana and Maine — Rubio finished in third place in the first three, and in fourth place in Maine. Trump and Texas Sen. Ted Cruz each won two states Saturday, further padding their delegate advantages over Rubio, who is well back in third place among the candidates in pledged representation at the Republican convention this summer.
