Sen. John Kerry (D-MA) is said to be furious at Sen. Mark Dayton (D-MN) "after he enthusiastically endorsed Sen. Hillary Rodham Clinton (D-NY) for president in 2008 at a Democratic-Farmer-Labor Party event in Minneapolis earlier this month," The Hill reports. "Dayton introduced Clinton as "the next great president of the United States."
Dayton told the Minneapolis Star Tribune that Kerry approached him on the Senate floor two days later ìwith daggers in his eyes and said, 'What are you doing endorsing my 2008 presidential opponent?' ... He was very serious."
