The amendment process is very difficult and time consuming: A proposed amendment must be passed by two-thirds of both houses of Congress, then ratified by the legislatures of three-fourths of the states. The ERA Amendment did not pass the necessary majority of state legislatures in the 1980s.

A new Constitutional Convention has never happened, but the idea has its backers. A retired federal judge, Malcolm R. Wilkey, called a few years ago for a new convention. "The Constitution has been corrupted by the system which has led to gridlock, too much influence by interest groups, and members of Congress who focus excessively on getting reelected," Wilkey said in a published series of lectures.
