Biden notched a 3-point lead in a CNN/SRSS poll published Tuesday, a 2-point lead in a Monmouth University poll published Sept. 3, and a 4-point lead in a Fox News poll published Sept. 2.

According to a RealClearPolitics average of North Carolina surveys conducted from Aug. 29-Sept. 14, Biden remains 0.9 percentage points ahead of Trump in general election polling.

Trump won North Carolina’s 15 Electoral College votes by 3.8 percentage points in 2016. The state has flipped between backing Democratic and Republican presidential candidates in previous election cycles.

Former President Barack Obama carried North Carolina in 2008, but lost there in 2012 to former Republican presidential nominee Mitt Romney.

The latest Suffolk University/USA Today survey also shows Democratic Senate candidate Cal Cunningham with a narrow edge over Republican incumbent Sen. Thom Tillis.

The closely watched race is one of a handful in which endangered Senate Republicans are battling for reelection, and it could decide whether the GOP maintains control of the chamber.

Cunningham leads Tillis by 4 percentage points among likely voters, 42-38 percent.

The RealClearPolitics average of polling for the North Carolina Senate race, which includes surveys from Aug. 29-Sept. 14, shows Cunningham ahead of Tillis by 3.5 percentage points.

Tillis is widely regarded as one of the most vulnerable Senate Republicans competing for another term in November, along with Maine’s Susan Collins, Colorado’s Cory Gardner and Arizona’s Martha McSally.

The Suffolk University/USA Today poll was conducted Sept. 11-14, surveying 500 likely voters in North Carolina.
