## Leadership by Congress

This query tool enables the user to select a single Congress, or many Congresses as a group, and to further select the position and the state or region. The database will then list all leaders meeting these criteria. It will also provide other information about them, including breakdowns by generation, birth year, age, longevity, and party.
