Kentucky governor primary results set up big challenge for incumbent Democrat Beshear

Kentucky Attorney General Daniel Cameron won the Republican primary for Kentucky governor Tuesday night. The Trump-backed candidate becomes the first major-party Black nominee for governor in the state's history. The victory sets him on a collision course with the state's incumbent Democrat Governor Andy Beshear, who easily won his primary.
