Pennsylvania's elections tell us how worried Republicans nationwide should be

Why is Pennsylvania important? Well, because what is brewing here serves as a microcosm of what is brewing across the country. If Republican House candidates, who hold a 13-5 majority in the congressional delegation, are starting to lose favor with voters here, nationally the Democrats are on their way to a celebratory election night one year from now. In short, the path to the House majority in Congress runs straight across Pennsylvania.

But this is also a place where indicators of how state legislative bodies across the country — those key down ballot seats that Republicans have been winning for nearly a decade — will hold up. As well as the Trump coalition.

Democrats won some key local races in the environs of Philadelphia and its suburbs — some of which broke historic records. Those wins were affected by local issues like building a new school in Lancaster, but Republicans nonetheless found themselves on the wrong side of voter sentiment.
