As undertones of racial politics make news, The Circus travels south, following two historic gubernatorial races with African-American candidates. In Florida, America's most unpredictable swing state, Democrat Andrew Gillum and Republican Ron DeSantis reap the benefits and face the challenges of being respectively progressive and pro-Trump candidates. Next door in Georgia, Secretary of State Brian Kemp and Democrat Stacey Abrams find themselves locked in a virtual dead heat despite being on opposite ends of a statewide voting controversy.

This special one-hour season finale is all about the midterms: before, during and after. In the run-up to election day, The Circus visits some of the high-profile campaigns to catch their final pushes. On election day, we're backstage and on set at The Late Show with Stephen Colbert, where John Heilemann and Alex Wagner are guests as the results are coming in. Then we cover the fallout of the historic election, from Trump's reaction to the surprising changes to the political landscape in Washington and beyond.
