The Reduced Shakespeare Company, a three-man act known for its ability to reduce serious subjects to comedy, comes to Cranston’s Park Theatre Friday. Watch as the trio performs “The Complete History of America (Abridged)” with a focus on Rhode Island politics and the upcoming elections. The performance will include a mock presidential debate between “Barack Obama” and “Mitt Romney,” and an opportunity for audience members to participate in a candidate Q&A session. The Reduced Shakespeare Company has performed at the White House and the Kennedy Center, and claims to perform London’s longest-running comedies.
