The Constitution of the United States is not merely a historical document, but rather it is the foundation for the rule of law that governs our democracy and limits the powers of government. Individual rights of life, liberty, and the pursuit of happiness are protected by the Constitution against potential infringements by government. Protecting the Constitution involves protecting the liberty of all Americans. One cannot differentiate between social and economic liberties when interpreting the Constitution, since an erosion of one will eventually lead to erosion of the other.
