In the second release of CNN’s New Hampshire poll, Sanders and Buttigieg outpace the rest of the candidates by 10 points, with Biden following.

Senator Bernie Sanders from Vermont takes the lead in the second release of the Democratic primary tracking poll conducted by the University of New Hampshire for CNN, which was conducted Wednesday through Saturday.
Sanders and former Mayor Pete Buttigieg are neck-and-neck, ahead of the other candidates by 10 points in the lead-up to the New Hampshire primary elections on February 11. Former Vice President Joe Biden polled third with 12%, while Senator Elizabeth Warren from Massachusetts polled at 9%.
Senator Amy Klobuchar from Minnesota, Representative Tulsi Gabbard from Hawaii, and entrepreneur Andrew Yang followed with 6%, 5%, and 4% respectively. Saturday’s post-debate interviews make up about a quarter of the tracking poll’s sample, and Klobuchar performed best out of all the days, while Warren performed her worst.

Both Sanders and Buttigieg held even with previous polling results. For supporters who have definitely decided who to vote for – 53% of those polled – Sanders leads Buttigieg, but the candidates poll more evenly among those who are still unsure. 28% of voters polled by the University of New Hampshire were still trying to decide. 
Among younger primary voters, voters without a college degree, and voters who identify as liberals, Sanders led Buttigieg, while the former mayor of South Bend, Indiana led among voters age 45 and up and those who consider themselves more moderate or conservative.
For Republicans surveyed, the numbers stayed the same as Saturday’s poll release, with 91% backing President Donald Trump, and 5% preferring former Massachusetts Gov. Bill Weld.
The CNN New Hampshire Poll was conducted by phone among a random sample of 384 likely Democratic primary voters and 227 likely Republican primary voters with a margin of sampling error of plus or minus 5% and 6.5%, respectively.
In a  Suffolk University poll released Friday, Buttigieg led Sanders by 1%, but the margin of error was 4%, effectively making the results of the poll a tie.
