Georgia US Senate race essentially tied in polls

The Politico has this:

The poll shows Chambliss leading Martin by three points, 50 to 47 percent, with three percent of respondents undecided. The first-term GOP senator's lead is within the poll’s four-point margin of error. . . .

“This thing’s going to be a nailbiter. We don’t know who’s going to turn out and we don’t know how it’s going to turn out, but it’s going to be a close race,” said InsiderAdvantage CEO Matt Towery . . .

Towery said the race was close enough that if Obama appeared at a rally just before the election and urged his supporters to vote for Martin, it might be enough to put the Democrat over the top.

“This whole race is on Barack Obama’s shoulders,” said Towery. “If he wants Georgia to vote Democratic, he could come down here the day of the election, hold a rally in Atlanta and get prepared to send people to the polls.” . . .
