Public Broadcasting Service is sponsoring debates for all Arkansas congressional races, and has invited all three Libertarian congressional candidates to participate. See this story. In the U.S. House races, there are Libertarians in two districts out of the four.
The Libertarian Party nominee for U.S. Senate, Ricky Dale Harrington, Jr., is the only opponent for incumbent Republican U.S. Senator Tom Cotton. The independent write-in candidate withdrew last month, and there is no Democratic nominee. Because Senator Cotton refuses to debate Harrington, PBS will air two interviews with Harrington.
A recent American Research Group poll shows Cotton at 49%, Harrington at 38%, and the remainder undecided.
