This year, three Democrats will challenge Republican Incumbent Richard Burr for the seat.
If the choice were between Burr and Democrat Elaine Marshall, who's currently North Carolina's Secretary of State, Burr would capture 54 percent of the votes.
But when it comes to race that's where the breakdown is.
Only 11 percent of African American voters would choose Burr, while 68 percent of African Americans would vote for Marshall.
When up against Democrat Cal Cunningham, a former North Carolina state senator, the overall gap narrows a bit. However, Burr still captures 48 percent of the votes, but 27 percent of those surveyed are still undecided about that match up.
And 28 percent of voters still aren't sure who they'd vote for between Burr and Democratic Lawyer Ken Lewis. Still, 49 percent would support Burr, compared to only 23 percent supporting Lewis.
Among African Americans, Lewis would capture 63 percent of votes. Burr would only capture 11 percent.
In all three scenarios, about 85 percent of Republicans would vote down the party line and support Burr.
Men and women are about equal in their support of Burr.
