ObamaGate the Movie Whom Would You Cast as the Players in Worst Political Scandal in United States History?

Translate:

If the shoe were on the other foot, there already would be several movies about a Trump plot to steal elections, but since the culprits in that are the ObamaGate players, it may take Kevin Sarbo and Kirk Cameron to get the job done! Whom would you cast as James Comey, Barack Obama, James Clapper, and Sleepy Joe, if all the Hollywood stars were available, and might it become actually a hot property after Devin Nunes comes out with what could be an entertaining summary for a movie script?
