The Pennsylvania Supreme Court made a ruling that effectively extended the deadline for election officials to receive mailed in absentee ballots. The election law passed by the state legislature required that the ballots must be received by the election officials by election day. The Pennsylvania Supreme Court, however, decided that ballots would be timely if postmarked by election day and received within three days after. The Court made that ruling invoking a provision in the state constitution that allows it to act to ensure free and fair elections in a "natural disaster". The disaster in this case being the corona virus pandemic.
The argument that Republicans made to the US Supreme Court is that the state supreme court lacked the power to make that change because the US Constitution states that the power to set the rules for elections is given to state legislatures and thus cannot be set by the state courts. US Const. Article I, § 4 and Article II, § 1.
The Supreme Court denied the request of the parties for expedited review of the case based because the Court would not have the time to fully consider the issue before the election. However, the matter is still before the Court and it remains to be seen whether it will indeed side with the Republicans and say that the US Constitution does not allow the state courts to alter the rules for elections set by the legislatures, even in the face of a natural disaster or pandemic.
If you think you want to get a law degree and become a lawyer you have plenty of time for that. You don't need to take a "pre law" program in college and can major in anything you want. The basic requirements to become a lawyer in pretty much every state is that you have a bachelor's degree (which can be with any major) and then attend an ABA approved law school (though California will allow you to attend a non ABA approved law school — a path I would not generally recommend unless you just can't get into an ABA approved program) and then after graduating from law school you sit for a bar exam and need to pass the fitness review. You'll take the LSAT exam as part of your admission to law school.
What you do want to do in college is look for courses/majors that emphasize reading comprehension, writing, and logical reasoning skills as those are the three fundamental skills every lawyer needs. If you want to do trial work, some courses or other experience in public speaking/debate would be good. Lots of different courses and majors can be useful. Math and computer science courses, for example, help develop logical reasoning skills. Indeed, many engineering and science areas are good for that. Courses in English and writing composition are obviously useful to develop your reading and writing skills. Any area that requires a lot of reading can help you develop the ability to read quickly and remember what you read. My major was business finance, and many of the courses in that program were helpful in developing skills needed for law.
You would want to take a major in something you enjoy and that you might like as a fall back career. If you enjoy it, you'll likely get better grades in it and the better grades you get the better law school you'll be able to get accepted into. You also need good scores on the LSAT exam to get into good law school programs. Law schools look at both your undergraduate grades and the LSAT score to determine whom they will admit.
