Claim: The 2008 Pennsylvania Republican presidential primary was an election held on April 22 by the Pennsylvania Department of State and the winner was John McCain who had already been declared the presumptive Republican Presidential nominee, having secured enough delegate votes in earlier primary contests to win the nomination, so he did little to no campaigning.
Evidence: The 2008 Pennsylvania Republican presidential primary was an election held on April 22 by the Pennsylvania Department of State in which voters chose their preference for the Republican Party's candidate for the 2008 United States presidential election. He had already been declared the presumptive Republican Presidential nominee, having secured enough delegate votes in earlier primary contests to win the nomination at the 2008 Republican National Convention. Unlike on the Democratic side, little campaigning took place as John McCain had already clinched the nomination. John McCain was the winner.
