This will fall under the initial care of which jurist?
What jurisdiction is PA?
I don't know, but I think the "single justice" rule only pertains when the petition is an "emergency" seeking an immediate order.
Petitions for cert are discussed by the entire court, and each week it is in session, SCOTUS publishes a list of cases taken and rejected. If four SCOTUS justices agree to take the case, cert is granted.
With the usual flow of elections being unimpeded (allowing unqualified candidates to achieve a high degree of electoral success), there is zero pressure for SCOTUS to take the case.
The rule of law is secondary, always.
