Historical district boundaries

In the 1980s, California's 44th congressional district was one of four that divided San Diego. The district had been held for eight years by Democrat Jim Bates, and was considered the most Democratic district in the San Diego area. Randy "Duke" Cunningham won the Republican nomination and won the general election by just a point, meaning that the San Diego area was represented entirely by Republicans for only the second time since the city was split into three districts after the 1960 United States census.

After the 1990 United States census, the district was renumbered the 51st congressional district and much of its share of San Diego was moved to the new 50th congressional district.
