LAST year, Real Housewives executive producer Andy Cohen noticed Donald Trump using so many pot-stirring tactics from the Bravo franchise that he began cataloguing them on Twitter. When the president used social media to cancel a White House invitation that N.B.A. champion Stephen Curry had not yet officially rejected, Cohen tweeted, “HOUSEWIVES PLAYBOOK: rescind invitations liberally! (See: Bethenny re LuAnn, Mexico; Bethenny & Ramona, Mexico).” Trump’s post-election digs about Hillary? “Keep bringing up fights from last season.” Trump’s excuse for not immediately calling Mexican president Enrique Peña Nieto following an earthquake? “Blame cell-phone reception.” Trump’s suggestion that Hillary Clinton’s presidential campaign colluded with the Russians? Tossing out bogus statements in desperate pleas “to stay on the show,” Cohen wrote.
