Sen. Bernie Sanders (I-VT) may have pulled ahead of Hillary Clinton in the New Hampshire polls in September, but the former secretary of state closed the gap again after the first Democratic presidential debate, according to a poll released on Friday by Suffolk University and the Boston Globe.

Among likely Democratic primary voters in New Hampshire surveyed following the debate, 37 percent favored Clinton and 35 percent favored Sanders. And among voters who tuned into the debate, Clinton led Sanders by five points.

When asked who they felt won the debate, 54 percent of voters said Clinton won, while 24 percent said Sanders won.

In a poll conducted by CNN/WMUR at the end of September, Sanders led Clinton by 16 percent among likely Democratic primary voters in New Hampshire. And a poll from CBS News/YouGov from earlier in September found Sanders leading Clinton by 22 points among likely Democratic primary voters in the state.

Suffolk University/Boston Globe surveyed 500 likely Democratic primary voters Oct. 14-15 with a margin of error plus or minus 4.4 percentage points.
