I just finished the book, Woodrow Wilson's War. What an astonishing piece of work he was...I was not aware of the full extent to which he trampled on the Constitution.

The reason Wilson asked Congress to declare war is pretty well understood. Wilson believed that government is the proper cure for national problems. The Federal Reserve System, that unaccountable and supra-constitutional invention that plagues us to this day, was one of his "cures" for a problem that did not exist.
