LRC Final Senate Maps: First Look


Nearly 5 million people. That’s the number of Pennsylvania’s who find their voices diminished in the final Senate Plan approved by the Legislative Reapportionment Commission.

The final Senate Plan appears to compromise Pennsylvania’s Constitution in favor of other considerations. A plan that balances legal considerations will minimize divisions while respecting minorities, creating compact and contiguous districts, and maintaining equal population.

When compared with at least two alternative plans, it is clear that the divisions in the final Senate Plan were not made to more closely meet other legal standards. 75% of the discretionary divisions were not absolutely necessary. This leaves nearly 40% of Pennsylvania’s population in counties, places, and wards with weakened representation in Harrisburg.

This Senate Plan was crafted through political compromise. But at what cost? Who can Pennsylvania residents count on to defend and uphold the Constitution above all other considerations? That is a question that will be answered in the days ahead.
