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”?
Actually Article IIII section 2 of the constitution enumerates the power of the Supreme Court that I of original jurisdiction in causes where a state is the party, but the USSC can turf this to a lower federal court. However, the USSC is the court of EXCLUSIVE jurisdiction in cases where a state sues a state.
What bars Texas or florida or Alabama from filing lawsuit against the state if New York ok grounds that the legislature who appoints the electors are being violated by New York in not having the option of voting for Trump? Seems to me that in reading the rule book the USSC can be forced into takin up the issue.
Going the road of writ of common laws, it seems that it can be filed, but the court must grant cert. (4 justices). State v state compels to court to hear it.
