CHARLOTTESVILLE, Va. (CBS19 NEWS) -- Larry Sabato and the University of Virginia Center for Politics hosted a discussion and a book signing with three guests, including former Senator Russ Feingold, the Democrat from Wisconsin that served from 1993 until 2011.

Feingold's book, called "The Constitution in Jeopardy," talks about the U.S. Constitution's history and the challenges facing democracy.

He also talked about the amendment process. He says for America to evolve, the Constitution must evolve with it.

"The Constitution cannot be changeless. Partly because it's very hard to do, we just simply have the hardest Constitution in the world to amend. Period. But if you put on top of that horrible partisanship, nothing can be fixed," said Feingold.

Other guests included co-author Peter Prindiville and Dr. Carah Ong-Whaley, the academics officer for the UVA Center for Politics. The discussion was followed by a book signing. The book is now being sold at UVA's bookstore.
