In a Marist poll conducted for NPR and PBS, Bernie Sanders holds a commanding 11 point lead nationally for the Democratic nomination.
Overall, 31 percent said they support Sanders, up nine points since the poll was last conducted in December. Businessman and former mayor of New York Mike Bloomberg came in second at 19 percent.
Former vice president Joe Biden slipped to third in the poll, with just 15 percent support, down from 24 percent in December. Senator Elizabeth Warren also take a hit, falling five points to 12 percent.
Moderates Amy Klobuchar and Pete Buttigieg both saw an increase in their support, but are each polling in the single digits in fifth and sixth place.
The survey also found Sanders with the broadest support of any candidates in the field. The Vermont Senator leads with young voters, progressive, both city and rural voters, college graduates and those without college degrees. He is also tied in first place with Joe Biden among black voters.
The survey of more 500 Democrats and Democratic-leaning independents was conducted from 13 through 16 February.
