PERRY, Ga. — Democrat Michelle Nunn and Republican David Perdue accused each other of offering false hope to voters during a rowdy debate Tuesday, arguing their opponent will not be able to advance anything if elected to Georgia's open Senate seat. From the moment the debate began before a crowd of a few thousand gathered inside an arena at the Georgia National State Fair, the candidates were on the attack and seeking to undercut each other's message of bringing change to Washington. The race is being closely watched nationally as Republicans seek to take control of the Senate and can't afford to lose the Georgia seat.
