What’s the liberal equivalent of climate denial?

Ezra Klein follows up the discussion his first post on Vox started, What’s the liberal equivalent of climate denial?.

"Does politics make Republicans dumber than Democrats? Paul Krugman thinks so. "Can anyone point to a liberal equivalent of conservative denial of climate change, or the ‘unskewing' mania late in the 2012 campaign, or the frantic efforts to deny that Obamacare is in fact covering a lot of previously uninsured Americans?" He asks. Jonathan Chait mostly agrees. "In American politics," he writes, "reliance on empiricism is an ideology" — and, to be more specific, that ideology is liberalism."

"No one can personally investigate the vast array of issues facing the country. In terms of getting the right answers, the most important decision people make is choosing whom to trust. In politics, that typically means choosing a party, or at least a political coalition. If one party is systematically better at assessing the evidence than the other that's a huge deal."

He doesn't answer the question, he just asks it again.
