ATLANTA (AP) - Georgia voters heard familiar arguments in the final U.S. Senate debate before polls open.

Republican David Perdue answered nearly every question Sunday by tying Democrat Michelle Nunn to President Barack Obama. Repeating attacks from his ads, Perdue repeatedly called Nunn a "rubber stamp" for the president, who lost Georgia twice.

Nunn said Perdue would continue the Washington gridlock that he blames exclusively on Democrats. Nunn, a former nonprofit executive, has campaigned as a "common-sense" moderate and said again Sunday that she wants to work across party lines.

A third candidate, Libertarian Amanda Swafford, said both Nunn and Perdue will perpetuate "big government."

Polls will be open Tuesday from 7 a.m. to 7 p.m.

If neither Nunn or Perdue get a majority, the two would meet in a January runoff.
