Conservatives respond to fear more strongly than liberals do, says one neuroscientist who studies political anxiety.

Conservatives’ bizarre, escalating obsession with Rep. Alexandria Ocasio-Cortez (D-N.Y.) reached a new level this week when The Daily Caller published fake revenge porn of the new congresswoman.

“Here’s The Photo Some People Described As A Nude Selfie Of Alexandria Ocasio-Cortez,” the Caller’s original headline read, before it was changed and the site posted a “we regret the error” message on Twitter. For the record, the photo is not of Ocasio-Cortez, despite what “some people” have said.

Since Ocasio-Cortez, a 29-year-old working-class democratic socialist, unexpectedly toppled powerful white male incumbent Joe Crowley in a June primary, she’s become an object of fixation among Republicans, especially Republican men. Conservative writer Ed Scarry posted a photo of her backside on Twitter, questioning whether her black suit was befitting of a “girl who struggles.” Right-wing media discovered that she ― like a lot of people named “Alexander,” “Alexandra” or some variant thereof ― went by the nickname “Sandy” in high school. A self-proclaimed “proud Christian Dad” on Twitter circulated a video of her dancing in a T-shirt in college as if it would be a career-damaging revelation. A Republican strategist referred to her as “the little girl” on Fox News, which runs segments about her constantly.
