The values of the Secular/Progressive/Statists are not those espoused by George Washington, Thomas Jefferson, Ben Franklin and the rest of the Founders. Those men all believed in the Constitution and the Rule of Law. To the Progressive, those things are just quaint anachronisms of a bygone era, to be followed if at all, only when it suits their purposes.
The history of our Constitution is inexorably linked to the history of our country itself. Just about every important moment in U.S. history therefore receives some coverage at the Center, from the American Revolution, to the Civil War, to Watergate.
