Breitbart has posted a very simple outline that answers whether President Barry could somehow delay the election or change the date:

Article 2 Section 1 Paragraph 4 of the Constitution: “The Congress may determine the Time of choosing the Electors, and the Day on which they give their Votes; which day shall be the same throughout the United States.”
