Sen. John Edwards (search), D-N.C., asked supporters to get out the vote on Tuesday and then chipped in himself by canvassing in a top battleground state — briefly.

"You're going to make the difference right here at ground zero," the Democratic vice presidential nominee told dozens of volunteers bundled up against the autumn chill as they set out to knock on doors in a middle-class neighborhood in Columbus.

For his part, Edwards stopped by six houses — an end-of-the-campaign effort staged for TV cameras and newspaper front pages.

"Nice to see you," the North Carolina senator said as he and former Sen. John Glenn (search),D-Ohio, tromped through leaf-strewn front yards, shaking hands of families waiting on their front porches.

Edwards posed for pictures, signed autographs and chatted up people in Ward 62, a swing voting precinct in central Ohio. President Bush won it in 2000 by 12 votes.

Presidential nominee John Kerry's (search) running mate was in the midst of a five-state swing on Sunday, packing his schedule with stops in Florida, Pennsylvania and three Midwestern states.

Edwards also did telephone interviews with two Hawaii newspapers. Polls show the race in the island state is close. Democrats are running ads in the state, and the ticket dispatched former Vice President Al Gore and Kerry's eldest daughter there, while Republicans sent Vice President Dick Cheney to the state.

Earlier Sunday, Edwards visited a predominantly black church in Jacksonville, Fla., and spoke at a neighborhood block party in Greensburg, Pa., before shaking hands with Ohio voters. Later, he headed to Waterloo, Iowa, and then to St. Paul, Minn.
