This (PDF) poll from Public Policy Polling has some very interesting information about the 2016 election:

Voters, and particularly independents, don’t have much tolerance for climate skeptics when it comes to the 2016 Presidential race. Only 38% of voters say they’d be willing to support a candidate who doesn’t believe global warming is caused by human activity, and by an 11 point margin they say they would be less likely to vote for such a candidate. When it comes to independents just 29% would be open to supporting a climate skeptic.

This is great news, and maybe it explains this news from New Jersey in response to President Obama's environmental action from yesterday:

A spokesman for New Jersey Gov. Chris Christie’s Department of Environmental Protection welcomed the Monday announcement, according to an Associated Press report.

“New Jersey Environmental Protection Department spokesman Larry Ragonese said the agency welcomed Monday's announcement. He noted that the state had already been moving actively toward cleaner energy initiatives and has beaten EPA target emissions rates for the past several years,” the AP wrote.

Christie himself has not chimed in on the news, but he appointed the Department of Environmental Protection head, so it's extremely unlikely that he's going to cross one of his own appointees so soon after his recent unpleasantness. Just about every other Republican who gets talked about as a 2016 contender has already gone on the record against Obama's climate change legislation. (One of them—howdy, Rand Paul!—even flip-flopped on coal so he could disagree with Obama.) This could make for some interesting debates, a couple years from now.
