LOUISVILLE, Ky. -- A feisty Mitch McConnell promised to take the fight to any opponent as the Senate's top Republican got a head start on a 2014 re-election campaign that could squeeze him between challenges from his own party as well as from Democrats.
Kentucky's longest-serving senator opened a campaign office in his hometown of Louisville on Saturday, about a year earlier than in his previous campaigns. It was a clear message to critics as he vowed to wage the "biggest and best campaign this state has ever seen."
