The '''nuclear''', or '''constitutional, option''' is a parliamentary procedure that allows the [[United States Senate]] to override its own rules by majority vote. Senate rules require a three fifths, or 60 vote, "supermajority" to reach a decision in many situations. If the [[presiding officer]] rules that a motion raises a constitutional issue, the matter then goes immediately to the full senate. Since the Senate decides a constitutional issue by majority vote, this procedure may be used to bypass any requirement for a supermajority. In general, the presiding officer follows precedent as interpreted by the parliamentarian. Unlike the Speaker of the House, he rarely uses his discretionary power. | The '''nuclear''', or '''constitutional, option''' is a parliamentary procedure that allows the [[United States Senate]] to override its own rules by majority vote.
