There has been a lot of internet chatter about the recent New York Times Magazine feature on “The Great Democratic Crack-Up of 2016.” The piece’s thesis is that Democrats face a dangerous insurgency, a mirror image of the Tea Party: left-wingers who threaten to shape the party’s messaging, win its primaries, and cost it elections even in blue states.

The author, Robert Draper, focuses on the Maryland 2016 Senate race, in which Rep. Donna Edwards, a heroine of the liberal blogosphere for unseating corporate hack Al Wynn in 2008, is challenging frontrunner Rep. Chris Van Hollen, who’s portrayed as a pragmatist. Draper is clearly on the side of the party’s monied corporate establishment. He refers to Wynn, a notorious lackey of big business contributors, as a “centrist,” and paints liberals as the enemies of politicians like Van Hollen who sometimes try to find common ground across the aisle.

But Draper ignores one of the most important issues to Democratic primary voters: climate change. Draper’s sole reference to climate is listing it as part of the implicitly unrealistic fantasy of liberals: “The outcome [of intra-party warfare], as [progressives] imagine it, would be a Democratic front line committed to income equality, an expanded social safety net and climate change doing battle with a G.O.P. that will continue to fight against tax increases, entitlement programs and environmental regulation.” If he looked more closely at climate change politics, though, Draper would see that they don’t fit into his neat narrative.
