What democracy looks like

We are fanning out across the state again to alert folks that they can help save our representative democracy by drawing a new voting map of Pennsylvania.

Slay the gerrymander. Draw the Lines, PA.


We're a nonpartisan resource for Pennsylvanians who want to end gerrymandering and improve democracy. We tell their stories, help them engage.  We offer them digital tools to draw their own election maps. Why? To prove that our state's people — whether 14, 44 or 84 — are ready, willing and able to take on this key work of democracy.  Our first mapping competition (total prize pool: $34,000) just wrapped up. A new one is underway.

Citizen Stories

Amanda Holt's Story

In 2010, she was a 29-year-old piano teacher living near Allentown. Then she noticed something … off in how her home state ran elections. She got curious. Then she got mad. And Pennsylvania politics was in for an earthquake.
