The 2009 Lehigh County Executive election was held on November 3, 2009. Incumbent Democratic County Executive Don Cunningham ran for re-election to a second term. He was challenged by Republican nominee Scott Ott, a satirical website publisher. Despite Cunningham's fundraising advantage and stronger name recognition, he was expected to win by a wide margin, but only narrowly defeated Ott,[1] winning 51–49 percent, a margin of just 862 votes.
Prior to the completion of Cunningham's second term, he resigned from office in 2012 to become the head of the Lehigh Valley Economic Development Corporation. Former County Commissioner Bill Hansell was appointed to serve out the remainder of Cunningham's term.[2]
