Not impeaching “Obama” is simply the final act of surrender. We the People of the United States have certain sovereign powers. We delegated some of them to a Congress of the United States in 1788.
Exercising our powers, the ones that we delegated to them, makes the scum who make up the Congress nervous, because in the proper exercise of these powers, they make some people angry or upset. Angry, upset people pose a threat to their continuance in office, a job which confers security and great wealth on any who hold it.
So, beginning with the abdication in 1913 of the Money Power, Congress has slowly been transferring OUR powers which we delegated to them to unelected and therefore invulnerable entities, which we cannot control.
This process is now nearly complete.
Not really... Impeaching a President takes both houses and you know that when one party controls a house of the President that impeachment is almost impossible.
Of course that is because politics today means Party instead of people representatives so there is a difference. Things have gone very wrong with local representation these days - both houses of Congress.
