Third, state courts have the final word on state constitutional interpretation. In other words, if you prevail on a state constitutional issue, the other side has no recourse to the U.S. Supreme Court, unless of course the state constitution itself violates the national Constitution.

Unsure if this is accurate but if so, how would one argue the PA constitution, as it is today, violates the national Constitution?

There are other examples of provisions of state constitutions having been found contrary to the US Constitution, but the first that comes to mind was decided in Romer v. Evans: https://en.wikipedia.org/wiki/Romer_v._Evans.

I suppose there may be an equal protection (14th Amendment) argument to be made in this instance, as in Bush v. Gore (and, indeed, in Romer), but I haven't studied the details here at all.

Specifically, Reynolds vs Sims case is referenced..one person, one vote
Maybe that’s how it gets to USSC?
