CNN’s Anderson Cooper and "The Nation" editor and publisher Katrina vanden Heuvel joined the attack on Bill Cunningham’s anti-Barack Obama comments at a rally for John McCain in Cincinnati, Ohio, comments that McCain himself repudiated. Cooper began his "Anderson Cooper 360" program on Tuesday by referring to Cunningham as a "talk show pit bull" and criticizing his use of Obama’s middle name. "Tonight: ugly words from a talk show pit bull about Barack Obama at a John McCain event, calling him a hack, using his middle name as a slander." Later, Cooper described Cunningham as a "a two-bit radio host." On Wednesday’s "Election Center" program on CNN, vanden Heuvel went even further than Cooper. "This talk radio guy is very unstable. He went from supporting McCain to Hillary and then Ralph Nader in one minute."
