I spent 1970-72 in Washington, DC, working with members of Congress and their staffers, and have had frequent contacts with them since. The subject of constitutional compliance has often come up. When I challenge the constitutionality of some proposed legislation, I often get that "You are the first person to contact us with that point."
Sen. John Glenn (D-OH) once admitted he disregards and has broken his oath of office to uphold the Constitution.
On July 16, 1996, the Senate Committee on Governmental affairs held hearings considering a bill to require Congress to specify for each new law which section of the Constitution gives it authority to pass the law. Sen. Glenn spoke out strongly against this requirement stating, "Why, if we had to do that we could not pass most of the laws we enact around here." He stated that the Clean Water Act, Endangered Species Act, the Americans with Disabilities Act and others could never have been passed if Congress had to find authority for them in the Constitution. He declared, "Americans just want us to solve America's problems of health and safety--and not be concerned if they can be constitutionally justified."
This is typical of the attitudes of members of congress, who, although few of them have a deep understanding of the Constitution, disregard it because their constituents don't make constitutional compliance a leading issue on which they decide who to vote for.
