Mike Mazzei, a former state senator and President Donald Trump's preferred candidate, has secured the Republican nomination for governor in Oklahoma, defeating Gentner Drummond by about 2,000 votes in the GOP primary runoff. According to campaign finance reports, Drummond outraised Mazzei in the weeks leading up to the runoff, bringing in $2.3 million compared to Mazzei's $816,000. This is despite Trump's public endorsement of Mazzei, which some analysts have noted has had mixed results this year, with five gubernatorial candidates backed by Trump failing to win their primaries. Mazzei will now face Democratic state Rep. Cyndi Munson in the general election.

Story summary
Former state Sen. Mike Mazzei, who was backed by President Donald Trump, has won the Republican nomination for governor in Oklahoma. Mazzei narrowly defeated state Attorney General Gentner Drummond by approximately 2,000 votes in the GOP primary runoff. The initial June primary was also tight, with Drummond finishing in first place by just over 1,000 votes ahead of Mazzei. Since no candidate secured a majority, the race went to a runoff. In the weeks leading up to the runoff, Drummond outraised and outspent Mazzei, bringing in $2.3 million compared to Mazzei's $816,000. Both candidates also loaned their campaigns significant sums: $11 million for Mazzei and $3 million for Drummond. Trump first endorsed Mazzei in May, and continued to support him throughout the campaign.
