Democrat Barack Obama's presidential campaign on Saturday repudiated a liberal talk show host's description of Sen. John McCain as a warmonger, a comment made to an audience that Obama later addressed. Ed Schultz, host of a nationally syndicated radio program that is based in Fargo, North Dakota, was warming up the crowd Friday at a $100-a-person fundraiser for the North Dakota Democratic party in Grand Forks when he tagged the Republican presidential nominee-in-waiting as a "warmonger." Schultz acknowledged using the term "warmonger" in a telephone interview Saturday. He said he has used the term many times on the air to refer to McCain because of his support for the war in Iraq. "He voted for this war. He's a perpetrator of the war. He's an advocate of the war," Schultz said. "In my personal definition, that's a warmonger." Obama was not in the room when Schultz spoke. The candidate spoke after a series of introductions by the state's three Democrats in Congress. Obama thanked Schultz and called him "the voice of progressive radio."
