Senator Bernie Sanders has opened a nine-point lead over fellow Democrat Hillary Clinton among party supporters in New Hampshire, according to an NBC News/Marist Poll released on Sunday.
The survey showed that 41 percent of Democratic voters would back Sanders while 32 percent would cast a vote for Clinton if the poll were held today and Vice President Joe Biden were on the ballot.
Draft Biden, a group urging him to put his name forward, said the poll showed "a deep desire among Democratic primary voters to have Vice President Biden join the Presidential race."
NBC also reported that its polling shows Clinton with a lead in Iowa, another state with an early voice in the nomination process, though her margin over Sanders has shrunk to 11 percentage points from 24 points in July.
