U.S. Senate candidates Democrat Erskine Bowles and Republican Elizabeth Dole will finish their tours of North Carolina this weekend.
The race, which many insiders initially assumed Dole would win because of her name recognition, is now considered a toss up, according to several polls.
With just a few days until the election, Bowles is continuing on into the final round of his statewide "Family First" tour, said Bowles spokesman Adrian Talbott.
Bowles' campaign will attempt to gain the few percentage points he trails by influencing undecided voters, he said. "This last push makes all the difference in the world."
Dole also will continue her bus tour of the state this weekend, said Dole press secretary Jerry Brown.
He added that the Dole campaign is not losing optimism because of the new statistics showing Bowles is closing in.
"Polls always tighten (the race) in the final days," he said. "We are at the point where the fence-sitters will choose a candidate."
The candidates' final pushes are focusing closely on specific issues, said Ferrel Guillory, director of UNC's Program on Southern Politics, Media and Public Life.
The intensity at the end of the race is directed at the 20 percent of voters registered as independent because the state is split almost equally between Democrats and Republicans, he said.
