Context: Edward Espenett "Ed" Case (born September 27, 1952) is an American Democratic politician who represented Hawaii in the United States House of Representatives from 2002 to 2007.

First elected to the House of Representatives in 2002 in a special election to fill the seat of Patsy Mink, who died of pneumonia, Case represented Hawaii's 2nd congressional district until 2006, when he chose not to run for another term in the House of Representatives so he could challenge Senator Daniel Akaka in the Democratic primary for Akaka's U.S. Senate seat.  Case lost the primary election 53%–46%. This is the electoral history of Ed Markey, a Democratic Senator from Massachusetts.  He was previously a Democratic Representative from Massachusetts, representing the 7th and 5th districts.
