SAN JUAN, Puerto Rico (AP) — Puerto Rico congressional representative Jenniffer González [R] defeated Gov. Pedro Pierluisi [D] in a surprise upset during a primary election held Sunday by their pro-statehood party. The two ran on the same ticket four years ago under the New Progressive Party, but González, a Republican, announced her plan to challenge Pierluisi, a Democrat, in early December. Public jabs between the two turned acrimonious during the campaign. Puerto Rico’s main political parties are divided by the island’s political status, so it’s common to find both Republicans and Democrats within the same party.
