"The facts of global warming demand our urgent attention," McCain said at the time. "Good stewardship, prudence and simple common sense demand that we act to meet the challenge and act quickly."McCain's support for cap and trade was not universal in the GOP, even then. But it wasn't a huge stretch, either. After all, the idea of controlling emissions with a market-based trading system has a Republican pedigree. The first President Bush used cap and trade to combat acid rain.In 2008, the biggest difference between McCain's plan to fight global warming and the Democrats' plan was how much each side wanted to rein in greenhouse gases: 65 percent or 80 percent. To environmentalists, that now feels like the good old days."Everyone agreed the sun rose in the east and set in the west," said Navin Nayak, senior vice president of the League of Conservation Voters. "Suddenly we emerge four years later, with a field of Republicans that are trying to tell us that the sun rises in the west, and we're not sure if it sets."Some Republican White House hopefuls — notably Rep. Michele Bachman of Minnesota — question the scientific consensus that greenhouse gases are likely a leading cause of climate change."Carbon dioxide is natural. It occurs in earth," Bachman said during a 2009 floor speech, as the House was considering cap and trade legislation. "Carbon dioxide is not a harmful gas. It is a harmless gas."Environmentalists give Huntsman and Romney some credit for at least acknowledging the science behind climate change. But they say simply admitting there's a problem is not enough."It would be like a presidential candidate saying, 'Yes, the debt is a serious crisis. But I'm not going to introduce any plan to deal with it,'" Nayak says.Republican candidates aren't the only ones who have changed their tune in recent years. The Pew Research Center points to a sharp decline in the number of Americans who even believe that global warming is happening, let alone that it's a serious problem.In 2006, 77 percent of Americans agreed there is "solid evidence" of global warming. By this year, that number had fallen to 58 percent. And just over a third believe that man-made carbon emissions are to blame."Most of that decline has occurred among Republicans and Independents," said Andrew Kohut, president of the research center. "The partisan gap is huge."Of course, these are the primary voters that Republican candidates need to appeal to. And they've been encouraged in their skepticism of climate change by fossil fuel interests, which have bankrolled an aggressive campaign against cap and trade.Even among Democrats, fighting global warming is not a high priority. So it's little wonder, in tough economic times, that GOP hopefuls have taken the public's temperature, and given this issue a pass.
