Bloomberg’s support increased by 15 points since last month’s poll. The billionaire, who is self-funding his campaign, also qualified for Wednesday night's debate with his performance in the survey.
Sen. Elizabeth Warren (D-Mass.) had a 5-point decrease to 12 percent support, based on the new poll. Sen. Amy Klobuchar (D-Minn.) had a 5-point increase to 9 points in the wake of her third-place finish in the New Hampshire primary.
