The two Democratic front-runners in the poll are neck and neck for the top spot, with Biden at 23 percent and Sanders at 22 percent. Buttigieg was the favorite for 18 percent of voters polled.

Warren has dropped to fourth in the Emerson poll, at 12 percent support. 

The poll was conducted Dec. 7-10 among 1,043 voters.
