For Mr. Trump, a victory by Mr. Bevin would become a talking point in his argument that Democrats are defying the will of voters in an effort to “overturn” the 2016 election, although the very fact that Mr. Bevin is fighting for survival may suggest that Mr. Trump is weaker here than he was three years ago.
Promoting his visit on Twitter on Sunday, Mr. Trump praised Mr. Bevin as “GREAT” but made no mention of local issues, instead urging Kentucky voters to “send a strong signal to Nancy Pelosi and the Radical Left Democrats.”
Mr. Bevin seized on that theme when warming up the crowd for Mr. Trump at the 23,000-seat Rupp Arena here. He opened his remarks with a warning against what he called creeping “socialism” and asked whether his supporters would “allow evil to prevail in this country.”
“Are we going to allow people like Nancy Pelosi and ‘the squad’ to impeach this president?” Mr. Bevin asked, referring to the House speaker and four liberal congresswomen Mr. Trump has repeatedly attacked. The crowd responded with a resounding no.
Mr. Trump was also joined onstage by Kentucky’s two Republican Senators, Rand Paul and Mitch McConnell, the Senate majority leader. Referring to the whistle-blower who first raised alarms about Mr. Trump’s policy toward Ukraine, leading to the impeachment proceedings, Mr. Paul called on the news media to “do your job and print his name,” drawing some of the evening’s loudest cheers.
Mr. Bevin’s rival, Mr. Beshear, is the son of a former Democratic governor, Steve Beshear, Mr. Bevin’s immediate predecessor. Mr. Beshear’s early lead seemed less about any deep affection he had earned from Kentucky voters than deep distaste for Mr. Bevin, a former Army captain and manufacturing executive with a combative political style.
