It took John Heilemann and Mark Helperin a little more than a year to write and publish “Game Change: Obama and the Clintons, McCain and Palin, and the Race of a Lifetime” in January 2009. By March 2012 the dramatic narrative version, Jay Roach‘s Game Change, debuted on HBO. It is therefore reasonable to presume that Heilemann & Halperin’s book about the 2016 election will be out by late ’17 or early ’18, and that an HBO movie about battle between Hillary Clinton, Donald Trump and Bernie Sanders will be airing by late ’19 or early ’20. There are many actors who could play all three, but on this morning’s Today show Bryan Cranston kick-started a conversation about his playing Trump. Cranston to Carson Daly: “He’s huge…this Shakespearean character…a serio-comic tragic character…who wouldn’t want to take a bite of that?” Wells to Cranston: If and when the role lands in your lap, don’t gain weight for it — wear prosthetic blubber (face, jowl, gut).
