The Hillary Clinton campaign is stepping up its criticism of Bernie Sanders, and a new poll provides a reason why: The two Democrats are neck-and-neck in Iowa and New Hampshire.
Clinton leads Sanders by just three points in Iowa, 48% to 45%, according a new NBC News/Wall Street Journal/Marist poll released Sunday.
Martin O'Malley is third at 5%, three weeks out from the Iowa caucuses on Feb. 1 that begin the nomination process.
Sanders, meanwhile, leads Clinton in New Hampshire 50%-46%, the poll said, with O'Malley at 1%.
The New Hampshire primary is Feb. 9.
