Isn't it a National Election because everyone in the country goes to the polls to elect the President on the same day?
BTTT
Sure, but only in that very specific sense. That's why I said we don't have a TRULY national election in the United States. We vote in elections organized and run by the individual States, largely under their own rules.
We don't even vote for President "nationally", we vote State by State for electors, who then vote as directed by the State at another election held in December.
This is the election where the President is elected. It is maybe the only "national" election we have, and the voters are a very specific, small group.
