There is no Federal Presidential election.
Look in the Constitution. It’s not there.
50 State Legislatures, acting separately, appoint 535 Electors. Congress appoints 3 since 1960.
Those 538 individuals choose the President.
The Founders debated AT LENGTH ways to involve, or not involve, Congress in the process, and they finally abandoned the Westminster system completely and put the States in charge.
What was the point of them doing that if we were only going to wind up with what you and others are calling a “Federal election”?
