Campus Martius Museum will host “Securing the Blessings of Liberty: An Overview of the U.S. Constitution” from 6-7 p.m. today.

The presentation by Marietta College political science Professor Mitchell Krumm is free and open to the public and sponsored by the nonpartisan group Living Democracy: Engaging Citizens and the museum.

Living Democracy described the talk as examining what the Constitution explicitly says as well as “the sometimes principled, sometimes pragmatic and sometimes ‘smoke-filled-room’ type politics that led” to its contents.

“This will point us to the more ‘unwritten’ elements of the Constitution that are often invoked in politics: the ideals and principles seen as inspirations or drawn from the document,” an announcement for the event said.

Living Democracy’s “Journey Along Democracy’s Trail” exhibit focusing on the development of democracy will remain on display at the museum through Jan. 29. After that, it will be on display at the Armory on Front Street from 10 a.m.-4 p.m. Monday through Friday, said Betsy Cook, chairwoman of Living Democracy.

Living Democracy also plans to start a Constitution study group in February. They will meet twice a month at the Armory to read and discuss sections of the Constitution. That will also be free and open to the public.
