On September 15, a gubernatorial debate was held that included all three Kentucky gubernatorial candidates, including independent Drew Curtis. See this story. In the 2014 general election campaign season, Kentucky had been one of a minority of states without any inclusive debates for any of the statewide offices (in 2014, Kentucky had a U.S. Senate race with three candidates on the ballot). Two lawsuits are still pending from the 2014 exclusion of the Libertarian nominee from all the 2014 U.S. Senate debates.
This story says the debate has boosted Curtis.
