Here is an article about the U.S. Senate debate in Arkansas on October 13. All four candidates who are on the ballot were included. They are the nominees of the Democratic, Republican, Libertarian, and Green Parties. The debate was hosted by Arkansas’s public TV station.
Looking forward to Free the Vote NC & Young Americans for Liberty at UNC Charlotte’s 2014 US Senate Debate coming up on Friday, October 17! We’ve invited all the candidates, but it looks like only the three write-ins and the Libertarian are planning to show up.
