The latest polls on the New Hampshire Democratic primary show Vermont Sen. Bernie Sanders and Indiana Mayor Pete Buttigieg as frontrunners in the race. 

A 7 News/Emerson College tracking poll shows Sanders at 30%, with Buttigieg at 20%. Minnesota Sen. Amy Klobuchar stands at 13%, while Massachusetts Sen. Elizabeth Warren comes in at 12%. Former Vice President Joe Biden has a particularly poor showing in this survey, with 11% support.

A Suffolk University/Boston Globe/WBZ tracking poll has Sanders at 24%, with Buttigieg coming in at 22%. Warren comes in at 13%, while Biden stands at 10%. 

Sanders has long been seen as the likely victor in the New Hampshire contest, as the state lies in his home region of New England. Yet, Buttigieg has been catching up, after his strong performance in the Iowa caucuses.

Sanders has been ramping up attacks on Buttigieg ahead of the primary, criticizing the Indiana politician for taking donations from billionaires. On Friday, Sanders read aloud newspaper headlines which say Buttigieg is a “big business candidate” and that he “has the most exclusive billionaires of any Democrat.” 

Buttigieg has said that the donations are necessary in order to take on the fundraising machine behind Trump, telling CNN that “this is a fight for our lives.” At the same time, Buttigieg said he is “not a fan of the current campaign finance system” and that his campaign has received mostly small donations of less than $40.

After the New Hampshire primary on Tuesday, the Nevada caucus will take place on Feb. 22. The South Carolina primary will take place at the end of the month, on Feb. 29.
