The last time a one-party Arizona delegation was elected on Election Day was in 1950, when voters chose 2 Democrats to serve in the 82nd Congress. [2] California's last Republican majority was in the 104th Congress. Democrats started with a narrow majority on Opening Day. But when Norman Mineta (D) resigned and Tom Campbell (R) won a special election to succeed him, the delegation was split, 26 to 26. Later, Walter Tucker III (D) resigned and left Republicans with a slim majority before the special election of Juanita Millender-McDonald (D) to fill Tucker’s vacancy. The last majority-Republican California delegation elected on Election Day was in 1956 when voters chose a delegation of 17 Republicans and 13 Democrats for the 85th Congress. [3] Georgia’s House delegation was last tied 6-6 in the 111th Congress after the resignation of Nathan Deal (R) and before the special election of Tom Graves (R) to fill the vacancy. [4] Hawaii’s House delegation was last tied 1-1 in the 111th Congress after the resignation of Neil Abercrombie (D) and the special election of Charles Djou (R). Hawaii’s House delegation had a 1-0 Republican majority for a brief period in the 101st Congress after the resignation of Daniel Akaka (D) and before the special election of Patsy Mink (D) to fill the vacancy.

[5] Idaho’s House delegation was last tied 1-1 in the 111th Congress. [6] In the 54th Congress, two Illinois seats were initially held by Democrats, but both Members lost election contests, resulting in an all-Republican state delegation.

Charles Halleck (R) was later elected in a special election to fill the vacancy. The last time a one-party Indiana delegation was elected on Election Day was in 1932 when voters sent 12 Democrats to the 73rd Congress.
