The supreme court doesn't get involved in state law matters because they can't and the only way to try to bring them in is arguing that:
a. a state court of last resort heard your case and made a ruling
b. that ruling was in error
c. that error violated federal law in some way
Asking SCOTUS to step in and determine if a state election violated laws passed by the legislature of that state after the state supreme court already ruled on the matter is only a good idea if you REALLY want to piss off the highest court in the land.
Even if they could do something like this, it is the LAST FUCKING THING a bunch of originalists would EVER do, you might see cases where more liberal interpretations could prevail, but who here thinks the liberal members of the court would happily disenfranchise millions of voters in multiple states to appease a big orange toddler throwing a hissyfit?
Go on raise your hands... no no, higher, all the way, now turn your palm towards your face, and slap yourself hard enough to knock some goddamn sense into you.
Some of these legal gambits may have fared better if filed by lawyers who weren't compete fucking morons, spelled properly, accused the right people, cited the right precedents, requested appropriate remedy, and above all else: HAPPENED WHEN THESE LAWS THEY'RE BITCHING ABOUT WERE CHANGED.
If your rights are violated by a law passed in march but you wait until you lose an election in november to care enough to file a suit in fucking december about it... you're shit out of luck asshole. You didn't care enough to check almost a year ago what was happening, you didn't even try to do anything about it before the election, and now that you lost it is suddenly not just the most important thing ever to remedy it... you want to throw away the votes which millions of people cast in good faith because you're a bitchbaby who can't handle losing?
Get completely and utterly fucked is how a layman would say it.
The courts and defendants will use several pages written by capable lawyers to explain all the ways you can go fuck yourself, exactly how hard you should go fuck yourself, and how long you can fuck yourself before you can cry about it again.
