A former executive at The Carlyle Group, a global investment firm, Youngkin pitched himself as a businessman and an outsider. He defeated six other nominees through ranked-choice ballots, which were calculated until the final round to determine the winner.
He put a heavy emphasis on cultural issues important to the Republican base. In recent days, Youngkin had picked up endorsements from prominent Republicans Sen. Ted Cruz of Texas and Oklahoma Gov. Kevin Stitt.
The announcement comes after the party’s “unassembled convention” Saturday, where GOP delegates voted at 39 sites across the commonwealth. Republicans picked the format after months of dispute about the process.
They also tried to draw on support from figures in Trump’s broader political world. Several members of Youngkin’s staff are veterans of Trump’s presidential campaigns. He also ran a TV ad with footage of Trump praising him by name during a White House event on trade.
Their strongest competition came from state Sen. Amanda Chase, a pro-Trump gadfly who revels in being known as a “firebrand” and “politically incorrect” and has a small, loyal following. She finished third and was knocked out of the race at the end of the fifth round of tabulations.
Republicans haven’t won any of the top three statewide positions, including governor, since 2009. Democrats took full control of the legislature in the 2019 elections, giving the party complete control of the commonwealth’s government for the first time in more than two decades.
General Election Day in Virginia is November 2.
