The choice of headline created a stir online, with “Renegade Jew” trending on Twitter today - though mostly through users making fun of it.
Harry Enten, a political forecaster, tweeted: “I called my mother only once not twice yesterday. #renegadejew,” while New York Magazine editor Jesse Singal wrote: “His parents wanted him to go to law school. He taught meditation instead. Renegade Jew: coming summer 2017.”
Mr Kristol, who founded and edits a conservative magazine called The Weekly Standard, has been vocal in his opposition to Mr Trump since he began his campaign for the nomination.
Last week, the conservative pundit told US television channel MSNBC that when it comes to Mr Trump, “unification means capitulation,” while yesterday he tweeted that “defending Trump really is a recipe for sounding like a fool.”
