The 2005 Lehigh County Executive election was held on November 8, 2005. Incumbent Republican County Executive Jane Ervin ran for re-election to a second term. She narrowly defeated engineer Kevin Ryan in the Republican primary, winning 53-47 percent, and advanced to the general election, where she was opposed by former Bethlehem Mayor Don Cunningham, the Democratic nominee. Cunningham defeated Ervin in a landslide, winning 62 percent of the vote to Ervin's 38 percent, largely over voter frustration at a 70 percent property tax hike, enabling him to become the first Democratic County Executive in county history.[1]
