Frankfort, KY – Ken Lucas has come out of political retirement to challenge fresman Republican U. S. Representative Geoff Davis.
He's vying for the congressional seat that he voluntarilly gave up after three terms to fulfill a campaign pledge.
Lucas is a conservative Democrat who formally entered the race when campaign supporters dropped off his filing papers at the secretary of state's office at the Capitol.
Lucas' return to politics sets up a re-match with Davis.
In his final re-election campaign in 2002, Lucas narrowly defeated Davis in the 4th district which stretches from the West Virginia border to the suburbs near Louisville.
Two years later, Davis defeated Nick Clooney to win the seat, whgich had been held by Republicans for decades until Lucas' victory in 1998.
Lucas stuck by his term limits pledge and retired from Congress
