By ANDREW P. NAPOLITANO The president is an ardent progressive. This dastardly philosophy of government was brought into the American mainstream 100 years ago by a Republican, Theodore Roosevelt, and a Democrat, Woodrow Wilson. Its guiding principle is the belief that government — not individuals — is the chief engine of human progress. If that means government tearing down rich persons to help poor persons, if that means the massive redistribution of wealth, if it means federal regulation of every conceivable occupation or productive endeavor, if it means fighting an unjust war, progressives are for it. Before the progressives, the dominant political thinkers in America were Madisonians.
