Sen. Richard Burr (R) is locked in a tight race with his Democratic challenger, Deborah Ross, in North Carolina, according to a new poll.
Burr is supported by 48 percent of likely voters in the state, followed by Ross, at 47 percent, according to a Quinnipiac University poll released Friday.
{mosads}The pair was tied at 46 percent early this month.
Burr is one of several vulnerable GOP senators up for reelection in a battleground state where polls have shown Democratic presidential nominee Hillary Clinton with a lead over GOP rival Donald Trump.
The Burr race is one that will help determine which party controls a majority in the Senate. Democrats need four seats if they retain the White House or five seats if Trump wins.
Clinton recently campaigned in North Carolina, where she stumped for Ross and encouraged voters to head to the polls early to support Democrats in the down-ballot races. The Quinnipiac poll also noted that early voting favors the Democrats in North Carolina.
Burr is currently leading Ross by 2.8 points in the RealClearPolitics average of state polls.
The poll of 702 likely voters was conducted Oct. 20–26 via landlines and cellphones and has a margin of error of 3.7 points.
