What you believe the constitution says or allows and what I believe it says or allows can be two different things. Many parts of the constitution are vague and open to interpretation and in fact I believe that is the way the authors intended it to be. That is why we have a Supreme Court to decide these things, and most people who say that the Constitution is being ignored tend to ignore or be unaware of the long list of decisions that the SC has handed down.
And the Supreme Court now has a political bias as well, which again does nothing to provide for an objective interpretation of the Constitution. And lately, the SC has shown themselves to be so completely our of touch with reality, their decisions have been head-scratching... case in point, the SC gutting the Voting Rights Act and essentially claiming racism is a non-factor in this country.
