Check your History.
There is no Constitution of the United States before 1787, and no ratification in force until June, 1788.
Now double-check your Constitution, because there is no requirement in the Constitution except that electors must be chosen before the safe haven date. In fact, there is not even a requirement that the states choose their electors by a popular vote.
An excerpt from a long article to refresh your memory:
No federal law regulated the 1788 federal election. In 1792, federal law permitted each state to conduct presidential elections in the state (i.e., to choose their electors) at any time in a 34-day period before the first Wednesday of December, which was the day set for the meeting of the electors of the U.S. president and vice-president (the Electoral College), in their respective states.

Thanks for the refresher, Fred. I’ll pull out the Constitution and review it again today.
