Clinton is favored to beat Sanders by 7 points, 49 to 42 percent, among registered Democrats and Democratic-leaning independents in the ABC News/Washington Post poll.
That's the closest margin ever between the pair in the poll, which recorded a 52-point lead for Clinton, 68 to 16 percent, last July. It's also the first time Clinton has slipped below 50 percent from Democratic-leaning voters.
The pair hold their own edge among voters split up by gender: Clinton leads 55 to 34 percent among women, while Sanders leads 53 to 41 percent among men.
Another national survey released Tuesday afternoon by NBC News and the Wall Street Journal similarly found Clinton holding onto a single-digit lead, besting Sanders by 9 points, 53 to 44 percent.
Clinton continues to hold strong leads over Sanders among older voters, minorities and women, while Sanders leads among independents, self-identified liberals and younger voters, according to that survey.
While national polls do not reflect the likelihood of candidates to win in certain states, they can help indicate momentum in the race. The ABC-Post survey was conducted mostly last week, from March 3 to 6.
Clinton and Sanders have faced off in forums two consecutive nights this week, with a debate Sunday night in Flint, Mich., and a Fox News town hall style-event on Monday evening. They will debate again on Wednesday evening Miami.
A weekly tracking poll released Tuesday by NBC News/Survey Monkey found Clinton expanding her lead by 4 points while Sanders lost 3, leading to a 17-point margin between the two.
The ABC/Washington Post poll of 1,000 adults overall was conducted via telephone with a margin of error of 6 points for Democrats and Democratic-leaning voters.
