The three-part documentary TV series “A More or Less Perfect Union,” produced by Free to Choose Network, will air on various PBS stations across the nation this month.

The documentary is a personal exploration of the U.S. Constitution by Justice Douglas Ginsburg, who served on the U.S. Court of Appeals for the D.C. Circuit and is now a senior justice on that court.

Ginsburg explores the Constitution and features interviews with, and perspectives from, constitutional experts of all political views—liberal, conservative, and libertarian. He examines the key issues of liberty in the U.S. both from a historical and contemporary perspective.

Among those issues are freedom of the press and religion, slavery and civil rights, the Second Amendment, separation of powers, and the number of ways that the Constitution’s framers sought to limit the power of the federal government.
