It says "the Time of choosing the Electors" but "the Day" of the electors voting.
I guess the Constitution would be more specific if it wanted election day to be on only one day.
So the electors have to vote on the same day but the voters have to vote within the same "time".
Thanks for the feedback all.
It would have to be the same in every state however the determine it.
Isn’t it somewhere in the Constitution that the election will be held on the first Tuesday after the first Monday in November?
