A new poll gives Georgia Republican Senate candidate David Perdue his biggest lead in over a month and within one point of avoiding a January runoff election against Democrat Michelle Nunn.

The latest Monmouth University poll shows Perdue at 49 percent among likely voters, with Nunn at 41 percent, the most recent indicator that the race is trending Republican after a series of surveys showed Nunn in the lead. Seven percent of voters remain undecided, while libertarian candidate Amanda Swafford is at 3 percent.

Perdue benefits from his lead among both men and women voters, as well as more Georgians saying they prefer that Republicans control the Senate. Additionally, just 38 percent of residents approve of President Obama.

But Nunn holds a significant edge among independent voters, who support her 50 percent to Perdue’s 33 percent. She also leads substantially in minority voters with 75 percent support to 14 percent going for Perdue.

If no candidate tops 50 percent of the vote on Tuesday, the leading two candidate will head to a January runoff, which may determine which party ultimately controls the Senate.
