Four of the five Republican candidates to succeed Gov. Nathan Deal in next year's election brought their campaign messages to Barrow County Saturday evening, as each of them vowed to provide conservative leadership for the state. Secretary of State Brian Kemp, state senators Hunter Hill and Michael Williams, and Marc Alan Urbach made brief pitches to a crowd of well over 200 people at the Winder Lions Club during the Barrow County GOP's annual large barbecue fundraiser.
