In an election season jam-packed with virtually every possible clash, America is now witnessing the apex of celebrity feuds: Donald Trump, short-fingered vulgarian, versus Lena Dunham, short-haired bohemian. This week, it happened; and if anyone was playing presidential pop-culture feud bingo, they have won.

The drama began during Dunham’s appearance at an award-ceremony luncheon on Monday, when the vocal Hillary Clinton supporter told “Watch What Happens: Live” host Andy Cohen that she would move to Canada if Trump won the election. “I know a lot of people have been threatening to do this, but I really will,” Dunham said, echoing the common refrain of several millions of Americans heard once every four years. “I know a lovely place in Vancouver and I can get my work done from there.”

Trump seemed practically giddy at the prospect. “Now I have to get elected because I’ll be doing a great service to our country,” the Republican front-runner said in response the next day, during a phone interview with Fox & Friends. “Now it’s much more important. In fact, I’ll immediately get off this call and start campaigning right now.”

He then bestowed upon Dunham the great compliment of a personalized Donald Trump insult: “a B actor [with] no mojo.”

Dunham has been a longtime Trump critic, and recently co-authored an essay slamming the mogul for refusing to address women’s issues, such as equal pay and access to birth control, while simultaneously raising a successful daughter who had access to those benefits.

As far as VF.com can tell, Trump had never addressed Lena Dunham before, but his comments appear to be out of line with the more presidential image he has been experimenting with in front of voters. Then again, Trump already have tired of his newly pseudo-serious character: a recent Politico report claims that the billionaire is working to rein in new campaign advisor Paul Manafort after he suggested that Trump’s raging, nativist outsider-dom was just an “image” to win the support of the plebes. Attacking Dunham—as perfect an embodiment as any of the elite Hollywood-politico-media axis—is the ultimate red meat for his fans.
