This year, the Libertarian Party of North Carolina has a contested primary for U.S. Senate between Sean Haugh, a long-time activist in the party, and Tim D’Annunzio, who recently joined the Libertarian Party and had run as a Republican for Congress in 2010 and 2012.
The two debated each other on April 5. Carolina Journal has this lengthy story about the debate. Carolina Journal is a monthly print publication, 22 years old, and an important web page for news about North Carolina government and politics. Thanks to IndependentPoliticalReport for the link.
