First last I checked PA was still part of America, meaning that for a candidate to be on the PA ballot they have to be eligible to run for the office in the first place. Secondly, Trump supporters have wanted a court ruling on this issue. Well there was one, and not only that but it was upheld by a higher court. Now of course there could be an appeal to the US Supreme Court, but does anyone really think that they are going to take such a time sensitive case with as much political ramifications as this on.... not likely.
I don't think SCOTUS will take it, but not because of any "time sensitive" concerns. They took Bush v. Gore exactly ,b>because of time-sensitive concerns, and handled the case quickly, by judicial measure of "quick."
On the political ramifications, SCOTUS will, I think, evade the question forever.
A good number of people have come around to understand the constitution is dead anyway, what with homo marriage and abortion being the 14th amendment, the 2nd amendment being relegated to the status of privilege, not a right, and assorted other contortions.
