Trader consensus favors former state Sen. Ralph Alvarado at 68% implied probability to win Kentucky's 6th Congressional District Republican primary on May 19, driven by his established name recognition from eight years in the legislature, superior fundraising, and a pivotal April 9 endorsement from the U.S. Chamber of Commerce highlighting his pro-business record. State Rep. Ryan Dotson trails at 10% following joint debates in February and March where both aligned on Trump-era policies, but lacks Alvarado's broader donor base and statewide profile in this open seat race vacated by Rep. Andy Barr's Senate bid. Lower-tier candidates like Adam Perez Arquette and Greg Plucinski lag due to limited visibility and resources, with early voting and final debates potentially shifting dynamics in the closed primary.
