1958 House Background
The 1958 U.S. House election chose members for the House of Representatives for the Congress beginning the following January. The app does not yet include an interactive map for this cycle.
Key Notes
- Unlike the Senate, every voting House seat is normally up for election every two years.
- District boundaries can change after each census, so historical House maps depend on the correct district geography for that cycle.
- This page currently shows the official chamber balance; a district map can be added when matching historical district geography and returns are available.
