Mr. Barr, who serves in the House, consolidated support among Republicans in part by securing the endorsement of President Trump.
Representative Andy Barr, a conservative Republican who earned the endorsement of President Trump in a hotly contested primary to succeed retiring Senator Mitch McConnell, won the Republican nomination for Senate in Kentucky on Tuesday, according to The Associated Press.
Despite the fact that Kentucky has a Democratic governor in Andy Beshear, the Senate seat is viewed as safely Republican.
Mr. Barr’s victory over Daniel Cameron, the former Republican attorney general of the state who was long seen as a protégé of Mr. McConnell, amounts to a lackluster ending to Mr. McConnell’s decades-long dominance in Kentucky politics.
Mr. Barr represents Kentucky’s Sixth Congressional District, which includes Lexington. He courted Mr. Trump’s endorsement from the moment he entered the primary. In his two-minute video announcing his candidacy, he made no mention of Mr. McConnell but brought up Mr. Trump four times.
His path to earning Mr. Trump’s blessing, as well as taking a clear lead in the primary, was not a forgone conclusion. For months, the primary was a tight three-way battle between Mr. Barr, Mr. Cameron and Nate Morris, a wealthy businessman with ties to Elon Musk, Vice President JD Vance and Donald Trump Jr.
Mr. Morris, a late entrant in the race, aimed to flood the zone with ads and commercials. An outside group backing him spent nearly $15 million on a paid media campaign, but it appeared to make little difference in polling, with either Mr. Barr or Mr. Cameron maintaining slight leads and Mr. Morris consistently running third.
