All five statewide winners carried it in November 2004. Although the Republican Party has historically been dominant in county-level politics, the Democratic Party has made substantial inroads this decade. In 2005, Bethlehem Mayor Don Cunningham unseated incumbent County Executive Jane Ervin to become the first Democrat to be elected to the office. Four of the nine commissioner seats and all row offices except for the District Attorney have held by Democrats since winning two at-large seats in November 2007. Lehigh County has a home-rule charter with four at-large and five district commissioners. In 2006 Lehigh County voters approved a county-charter amendment to combine the offices of Clerk of Courts, Register of Wills, and Recorder of Deeds into the office of the Clerk of Judicial Records. Clerk of Courts Andrea Naugle won the new office in November 2007.
