Lucia Graves of the National Journal writes there’s evidence that efforts are paying off to make climate-change denial an issue of vulnerability: “specifically, that along with other defining issues like gun-control, gay marriage, and immigration, the media is increasingly asking GOP candidates about their views on climate change.”

“Climate change, as National Journal‘s Ronald Brownstein has observed, is one of several issues that matter to core Democratic constituencies, including and maybe even especially young voters. By embracing priorities that matter to these groups, like climate change, gun control, and gay marriage, Democrats are hoping to appeal to what Brownstein describes as a ‘coalition of the ascendant.’”
