That wasn't the question I asked.
Doesn't the Constitution declare the date (singular) for voting for POTUS?
The only Const. requirements for a time line is that the new President will take over from the old President at noon on the 20th of Jan.
Thats all.
So in theory you could have the elections in Dec. or whenever. as long as you made room for the Electoral College to vote and decide the Pres.
The Constitution doesn’t even declare that POTUS will be voted for. The Constitution says each state legislature will determine how they’re electors are chosen, then the ELECTORS (not you and me) vote for president when they gather as the electoral college. For quite a while some states had the legislature directly appoint electors, no popular vote at all.
Article II, Section 1:
The Congress may determine the time of choosing the electors, and the day on which they shall give their votes; which day shall be the same throughout the United States.
US CODE: Title 3, Section 1
The electors of President and Vice President shall be appointed, in each State, on the Tuesday next after the first Monday in November, in every fourth year succeeding every election of a President and Vice President.
