FRANKFORT — Libertarian U.S. Senate candidate David Patterson has asked a federal judge to order Kentucky Educational Television to include him in the station’s televised debate on Oct. 13.

Republican Sen. Mitch McConnell and Democratic candidate Alison Lundergan Grimes have both said they will participate in the debate. It will likely be the only time voters will see the two debate on statewide television before the Nov. 4 election.

Patterson, who is a police officer in Harrodsburg, is also on the ballot but was not invited to the debate. His lawsuit alleges KET officials are excluding him from the debate because of his political views—something the U.S. Supreme Court has said public broadcasters cannot do.

A call to a KET spokesman was not immediately returned.
