The new poll finds Sen. Sanders with 52% support among Democratic primary voters in New Hampshire, while former Secretary of State Clinton, long considered the front-runner for the 2016 Democratic nomination, receives 30%. Recent polls have shown Sanders’ lead growing in the Granite State, but this would be the first to show the Vermont Senator over 50%. 

Possibly more worrying for the Clinton campaign is her performance in Iowa, where Sanders now leads by 10 points, with 43% to Clinton’s 33%.

Until recently Clinton had retained an edge in Iowa, the other first-in-the-nation voting state along with New Hampshire. A recent CNN/ORC poll found the pair tied among likely Iowa caucus voters.
