In April I laid out what I saw as Democrats’ best path to winning 102 seats and a majority in the PA House. It looked a little different than I thought it would, but they did it. A thread:

The Fall Line is an ancient geological feature. Lined by a string of waterfalls, it divides the hills of the Piedmont region from the Atlantic coastal plain.

That’s true, but incomplete. For instance, swathes of Bucks and Delaware Counties swung right, while Northwest Philly neighborhoods like Roxborough got bluer.
