Martha Marks, the president of Republicans for Environmental Protection, dates the rift to the social unrest of the late 1960s. "Sportsmen tend to be conservative or moderate--and they tend to honor tradition," she says. "So when sportsmen saw many of the same people who were carrying antiwar signs also carrying pro-environment signs, they linked the two, and a stereotype emerged. If you were proenvironment, you must be a long-haired, commie, pinko liberal. And if you were a liberal, you were against gun rights and for animal rights. That was absolutely not true: The greatest environmentalists in this nation's history have been Republicans. But the label stuck."
