Stockard on the Stump: It’s not debatable, Blackburn shifting for money

U.S. Sen. Marsha Blackburn avoids debates in the Republican gubernatorial primary while hosting a post-election fundraiser in Atlanta. Her campaign donated $4.8 million to a dark-money group targeting Rep. John Rose, and a separate group criticizes her fundraising practices. Blackburn claims conservative unity is more important than debates ahead of the August 6 primary.
