Today’s comic by Mark Fiore is The math of Democracy: • Conrad Burns, former Montana senator, dead at 81: The three-term Republican raised cattle and built a radio empire (by Montana standards) before winning election to the Yellowstone County Commission in 1986. Then, he defeated two-term Democratic Sen. John Melcher in 1988, calling him "a liberal who is soft on drugs, soft on defense and very high on social programs." His three terms made him the longest serving senators in Montana history.
