Thomas F. Wilson as Donald Trump
Kevin Spacey as Mike Pence
Jesse Eisenberg as Jared Kushner
Emily Baldoni as Ivanka Trump
Jessica Walter as Nancy Pelosi
Jeffrey Tambor as Rudy Giulianni
Bill Murray as Joe Biden
Larry David as Bernie Sanders (duh)
Maya Rudolph as Kamala Harris (double duh)
Charles Dance as Mitch McConnell (idk if he could do a southern accent)
Taran Killam as Pete Buttigieg
Jeff Garlin as Chris Christie
Jesse Eisenberg does have the same vacant, soulless eyes as Kushner. That's why he was so good as Mark Zuckerberg.
Also I don't know if a quasi-'Arrested Development' reunion would be a good idea in a serious political biopic. I would just be distracted watching and waiting for them to their impersonations of chickens.
