Former Vice President Joe Biden should be weary of a poor showing in the New Hampshire primary, according to New York Times national political correspondent Jonathan Martin.

During an interview with Boston Public Radio in Manchester, N.H., on Monday, Martin said that for candidates like Biden and Senators Amy Klobuchar and Elizabeth Warren, the primary could be their last chance of showing not just voters, but donors, that they still have a viable campaign.

“New Hampshire has a history of culling the field, of vaulting candidates forward and leaving others behind in the snow banks here on the Merrimack River, and I think that’s going to be the case here as well,” Martin said. “If you’re not showing strength. If you’re not coming in that sort of top two along with [Pete] Buttigieg and [Bernie] Sanders it’s just difficult to go forward. In large part because you’re not going to have the money to sustain a campaign to go forward.”
