Bernie Sanders and Joe Biden are locked in a close race in North Carolina's Democratic presidential primary, which will award a healthy chunk of delegates on Tuesday, according to an NBC News/Marist poll.
The Vermont senator gets 26% of support among likely Democratic primary voters, narrowly topping the former vice president at 24%. The gap falls within the survey's margin of error.
Former New York Mayor Mike Bloomberg trails the pair with 15% of support. Sen. Elizabeth Warren, D-Mass., follows with 11%.
Here's how the rest of the field fares in the North Carolina poll:
After Biden's resounding victory in South Carolina on Saturday, North Carolina will offer another test of his support in states with a large share of black voters in the Democratic electorate. Bloomberg will be on the ballot for the first time Tuesday, and has drawn significant support in Super Tuesday states as he piles hundreds of millions of dollars into his campaign.
As Sanders narrowly leads Biden in the pledged national delegate count, both have cast themselves as the best candidate to defeat President Donald Trump in November. North Carolina, which supported Trump in the 2016 election, could prove competitive in the general election, according to the NBC/Marist poll.
Sanders gets 48% of support among registered voters in a hypothetical race against Trump, while the Republican incumbent gets 46%. Biden leads Trump by a slightly wider margin in a head-to-head matchup: 49% to 45%.
In November, one of the most vulnerable Senate incumbents will also try to defend his seat in what could be a swing state. Sen. Thom Tillis, a Republican, has tied himself closely to Trump as he runs for reelection.
In the primary to face Tillis, former state Sen. Cal Cunningham has a wide lead over state Sen. Erica Smith, 51% to 18%.
In a potential general election race, Cunningham has a 48% to 43% edge over Tillis.
The NBC News/Marist poll, taken from Feb. 23 through Feb. 27, surveyed 2,120 registered voters with a margin of error of plus-or-minus 2.6 percentage points. It polled 568 likely Democratic primary voters with a margin of error of plus-or-minus 5.1 percentage points.
