Sen. Mark Pryor, D-Ark., will launch a television ad campaign on Friday — 17 months before this cycle's most vulnerable incumbent faces voters in the general election. "It’s an ad in response to the attacks we’re getting on both sides," Pryor campaign manager Jeff Weaver said. "These outside groups are trying to affect the election. So we’ve produced an ad." Pryor has been hit on the air by the conservative groups Club for Growth and Senate Conservatives Fund for his ties to President Barack Obama. New York Mayor Michael Bloomberg's super PAC, Mayors Against Illegal Guns, just launched a $350,000 ad buy hitting Pryor for his vote against expanded background checks.
