Rep. Tom Cole (R-Okla.), the chair of the House Appropriations Committee, won the Republican primary for Oklahoma's 4th Congressional District, securing 65-67% of the vote against political newcomer Paul Bondar, who financed his campaign with over $5 million of his own money. Cole, endorsed by former President Trump, emphasized his extensive experience and deep ties to his state, while Bondar criticized Cole for his bipartisan efforts and support for aid to Ukraine. Cole will face the Democratic primary winner and Independent candidate James Stacy in the November general election, aiming for his eleventh term in a heavily Republican district. The race was notably expensive, with significant financial contributions from both candidates and outside groups. Cole has represented his district since 2003 and is likely to continue his tenure given the district's conservative leaning.
