This is a proof-of-concept of an idea from Dr. Sam Wang at Princeton Election Consortium to create an app allowing people to enter an address and find nearby competitive Congressional Districts for the 2018 election.

Competitive districts, shaded in purple, are those defined as Tossup or Lean D or R, by the Cook Political Report. Click on a district for more information.

Note: The map works best on desktop or laptop systems; may be a little flaky on mobile devices.
