New Jersey Gov. Chris Christie told Kentucky Republicans that President Barack Obama was “posing and preening” instead of working to resolve pressing issues facing the country.

“He is the most ill-prepared person to assume the presidency in my lifetime,” Christie told some 600 Kentucky Republicans at a Lexington hotel. “This is a guy who literally is walking around in a dark room trying to find the light switch of leadership.”

Christie was in Kentucky to deliver a pep talk to state GOP leaders. The state’s presidential primary is Tuesday, though it will have no significant impact. Former Massachusetts Gov. Mitt Romney is the presumptive Republican presidential nominee.

In his remarks, Christie focused entirely on the general election, drawing a standing ovation for his biting remarks about Obama.
