SAN JUAN, Puerto Rico — Puerto Rico congressional representative Jenniffer González defeated Gov. Pedro Pierluisi 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.
''What happened is very painful, and I didn't expect it, but let no one think that I'm going to slow down in the remainder of this four-year period,'' Pierluisi said late Sunday as he congratulated González.
He addressed his supporters briefly as González celebrated with hers while results continued to trickle in.
González obtained 56% of the vote compared with Pierluisi's 44%, with an estimated tens of thousands of votes still uncounted. She is the first female gubernatorial candidate to secure a primary win for the New Progressive Party.
''Positions do not belong to politicians ... they belong to the people,'' González said during a speech shortly after Pierluisi conceded. ''I commit to being on the streets, to listen to people.''
As of Monday, Puerto Rico's elections commission had not yet provided updated numbers and was still counting votes.
