The 2008 New Progressive Party primaries were the primary elections by which voters of the New Progressive Party (PNP) chose its nominees for various political offices of Puerto Rico, namely the position of governor, for the 2008 general elections. Resident Commissioner Luis Fortuño was selected as the nominee at the primary elections held on March 9, 2008. He would go on to win the 2008 general election as well.
Pedro Rosselló had come from a defeat against AnÃÂbal Acevedo Vilá at the 2004 elections. Despite that, he managed to gain a seat in the Senate. After an unsuccessful power struggle within the Senate to gain the presidency of the body, it was speculated that Rosselló would make another attempt at being elected Governor for the 2008 elections.
The power struggle had caused a division within the party, with the faction that supported Senate President Kenneth McClintock (called the "Auténticos") being expelled from the party during the previous year. Although the Supreme Court allowed them to run in the PNP primaries, Pedro Rosselló, then President of the party, still vouched for a "vote of punishment" against the senators, which he called "traitors".
The New Progressive Party held primaries on all 8 of the senatorial districts.
The Popular Democratic Party held primaries on 30 of the 40 representative districts.
The New Progressive Party held primaries in 34 of 78 municipalities.
The primaries were held on March 9, 2008. In it, Fortuño comfortably defeated Rosselló to win the spot for Governor at the 2008 elections. Also, Pedro Pierluisi defeated Charlie RodrÃÂguez and Miriam RamÃÂrez de Ferrer with 60% of the votes to win the spot for Resident Commissioner.
During and after the primaries, members of the New Progressive Party (PNP), like Senator Norma Burgos, claimed they saw voters affiliated with the opposing Popular Democratic Party (PPD) voting in the PNP ballots. Also, Maritza Vázquez, Electoral Commissioner of PPD representative Conny Varela, admitted in 2010 that "thousands of 'populares' voted on that election'". Some of the supporters of Rosselló maintain that this "crossover" was crucial in Pedro Rosselló's defeat against Luis Fortuño.
As a result of Rosselló's loss in the primaries, a group of his supporters started a campaign to have him elected through "Write-in" voting.
Despite Rosselló's call for a "vote of punishment" against the "Auténticos", all but one of the eligible candidates from that faction were elected in the primaries. Carlos DÃÂaz was edged out of the election race by Senators Roberto Arango and Kimmey Raschke. Migdalia Padilla, Lucy Arce, and Jorge de Castro Font were all elected. Kenneth McClintock had decided not to run for Senate, while Orlando Parga refused to return to the party after his expulsion, and started an independent campaign.
