Example: Gingrich says he'll ignore the courts and steamroll right over any decisions they make. That scares the bejeezus out of me, that someone could say that, out loud, in public, during the present campaign, and still expect to be elected.
Not true. If you followed the conversation at all, he never said any such thing. What he said did not even apply to the Presidency but to the Congress. The President is powerless in that regard but the way the news played it, they made you believe the nonsense they were pushing.
Now, on to the truth. If congress decides to impeach a judge it is up to the Senate to hold a trial. Judges are not above the law and in fact the judiciary is supposed to be the weakest of the branches of government. They are not supposed to make law but judge based on law. The judge Gingrich mentioned made a decision that was against both the Constitution and the law. This judge should be impeached. If he refused to come before Congress to answer questions, then do you think he should be above the law? Do you think he has the right to refuse without consequences? Remember, in this instance, Congress is the law.
As an interesting side-note, Thomas Jefferson feared that the Supreme Court would assume too much authority and rule on the Constitution in favor of big government.
