When vacancies happen in the representation of any State in the Senate, the executive authority of such State shall issue writs of election to fill such vacancies: Provided, That the legislature of any State may empower the executive thereof to make temporary appointments until the people fill the vacancies by election as the legislature may direct.
Taken verbatim from the 17th Amendment of the United States Constitution. In layman's terms: When a senate seat is vacant, the governor of a state has the power, right, and duty to appoint a new senator until elections take place. Providing that his state legislature has given him the authority.
Illinois is one such state that does allow for the governor to appoint senators when there is a vacancy. Governor "Blago" has done just such a thing and has the whole power of the United States Constitution behind him. Yet Harry Reid, the president of the senate, refused to allow the lawfully appointed Roland Burris be seated as a United States Senator. This is a direct breach of his oath to uphold and protect the Constitution. It does not matter what "Senate Rules" say,or how long they have been in effect. In fact that is a scary topic all in itself. Is it possible for Senate rules to subvert and override the Constitution itself?
For these crimes against the United States and it's people. Senator Reid should be arrested, indicted, tried, and if convicted swing from the nearest tree.
I understand there are those out there that would argue the governor is corrupt, his appointment might be for personal gain, etc... All this does not matter for several reasons. First, he has acted within his Constitutional authority to appoint someone to a vacant senate seat(that should be enough there), secondly, ever heard of that "innocent until proven guilty" phrase?, and lastly he was acting within his Constitutional authority.
