Bernie Sanders is all but guaranteed to win New Hampshire, according to a polls-plus projection by FiveThirtyEight, the data-driven website run by polling guru Nate Silver.

Silver's team calculated the Vermont senator’s chances to win the first-in-the-nation primary on Tuesday as greater than 99 percent, based on a weighted average of 84 polls dating back to last year.


In the latest New Hampshire polls, Sanders maintains a double-digit advantage over Hillary Clinton, and he leads her by nearly 13 points in the RealClearPolitics average.
