This story says that support for Ricky Harrington is growing, as a result of the hour interview on the Public Broadcasting stations in Arkansas. PBS wanted debates, and did sponsor inclusive debates for the U.S. House races in Arkansas. But in the U.S. Senate race, Cotton refused to participate, so PBS gave the entire hour to Harrington. Harrington is the Libertarian nominee. There is no Democrat in the race. Thanks to Liam Callahan for the link.
