Liz Cheney talks about democracy at Crystal Bridges

• Caryl Stern, executive director of the Walton Family Foundation, moderated.

"I really can't think of anything more fitting at the end of … what was a sad day in many ways — but a day that was dedicated to the Constitution — than to be able to be here and to actually see an original copy of the Constitution," Cheney said.

Catch up quick: To a crowd of more than 500, Cheney stressed how important it is to teach and learn history and how democracy needs a larger pool of serious candidates to run for higher office.

What they're saying: "We have an obligation to educate ourselves. We have an obligation to make sure that, as Americans, we understand how our institutions work, we understand the protections that the Constitution gives," Cheney said.

• She added: "If we only defend the Constitution when it serves our political purposes, then we won't ever be able to call on it as a shield when we need it."
