The Circus: Inside the Greatest Political Show on Earth Season 4 (Part 2)

Tracking the largest field of presidential candidates in U.S. history, THE CIRCUS returns to SHOWTIME with eight new episodes. Starting on Sunday, September 22 at 8 p.m. ET/PT, the network's most-watched docuseries will continue its fourth season, which averaged more than one million weekly viewers earlier this year. Co-hosts John Heilemann, Alex Wagner, and Mark McKinnon will crisscross the country as an unprecedented cast of Democratic candidates barnstorm key states in their quests to face off against Donald Trump in 2020. Meanwhile, the president is pursuing re-election amid a growing threat of impeachment and looming international crises.
