Back in 2012, HBO and director Jay Roach offered up a four-years-later post-mortem on the 2008 presidential election—and specifically the effects that dark horse vice presidential candidate Sarah Palin wrecked upon it—in the form of the TV movie Game Change. The film was based on the book of the same name by journalists John Heilemann and Mark Halperin, who’ve since written a sequel about the 2012 race, and are currently hard at work on a third book documenting Donald Trump’s presidential upset last year.
