It is clear from the impeachment of Bill Clinton that public opinion is terribly important and it no doubt was the intentions of the framers of the Constitution that the will of the people be taken into account in the matter of ousting a president or else they probably would've put it in the hands of a court or some other body not as responsive to the will of the people.
I said not as responsive because, clearly, the history of the United States Supreme Court reveals that it is not indifferent to public opinion. One need only reflect on the court packing scheme which did not generate enough public opinion to persuade Congress but came close enough to intimidate the court.
I do not think it is altogether a bad thing that public opinion is felt by our institutions. We always have the tension in government between the role of the elites and the rule of the mob that is why we have a written constitution and that is why we impeach leaders who are found to be without integrity or, officially, to have "committed high crimes and misdemeanors" -like Bill Clinton.
Obama as an Usurper is not entitled to a trial in the Senate. He is an Usurper, not a sitting president.
The facts have to be established by SOME formal trial procedure. The putative Executive Branch cannot be tried by the Judiciary, even though Hussein is in all likelihood a fake ass counterfeit usurper. That would be a violation of seperation of powers. The FACT of it must be established using the only constitutional method to remove a POTUS, the Article I Sec. 3 impeachment process, and or the XX amendment. After he is a private citizen, we can try him for all the criminal offenses that he has committed.
None of this changes the fact that I would enjoy dragging him from the Oval Office by his big jug ears.
