Help slay the gerrymander. Draw the Lines, Pennsylvania


We're a nonpartisan resource for Pennsylvanians who want to end gerrymandering and help democracy work better. We tell their stories, help them connect, provide ways to engage.  We offer the digital tools needed to draw a valid election map. Why? To prove that our state's people — whether 14, 44 or 84 — are ready, willing and able to take on this key task of democracy. To slay the gerrymander, we’re running mapping competitions (with prizes of up to $5,000) through 2021. Learn more.

Want to win $5,000?

You must complete your map by Friday!
