[S]lavish devotion to coal and oil, and sneering at environmentalism, contradicts the G.O.P.’s long tradition of environmental stewardship that some Republicans are still proud of: Teddy Roosevelt bequeathed us national parks, Richard Nixon the Clean Air Act and the Environmental Protection Agency, Ronald Reagan the Montreal Protocol to protect the ozone layer and George H. W. Bush cap-and-trade that reduced acid rain. Does the G.O.P. really think it will attract the idealism of next-generation voters with mottos like “Coal = Jobs”?
