Ralph Alvarado holds a commanding lead in the Republican primary for Kentucky's 6th Congressional District ahead of the May 19 vote, driven by President Donald Trump's May endorsement that positioned him as a strong "America First" contender with ties to the MAGA movement. Alvarado, a former state senator and physician, has also secured backing from the U.S. Chamber of Commerce, Speaker Mike Johnson, and several Kentucky Republican lawmakers, reinforcing his frontrunner status in a crowded field that includes state Representative Ryan Dotson and Greg Plucinski. Trader consensus in the prediction market reflects these endorsements and Alvarado's established name recognition in central Kentucky, though any last-minute shifts in voter turnout or unexpected campaign developments could still influence the final tally before primary day.
