According to the Constitution, if a presidential election is not decided by Inauguration Day on Jan. 20th then the Speaker of the U. S. House of Representatives becomes president until the election is decided, another reason to vote Republican so that Nervous Nancy would not become president of the United States (oh the horror!) The Republicans must beware that Nancy may try to change the swearing-in date for Congress from Jan. 3rd until after the 20th, to prepare for the Republicans taking back the House.
