(CNN) Former Vice President Joe Biden tops the Democratic primary field in the early voting state of South Carolina, according to new polls from Quinnipiac University and the University of North Florida.

About a third of likely voters in South Carolina plan to support the former vice president, according to both polls.

Quinnipiac has Massachusetts Sen. Elizabeth Warren and Vermont Sen. Bernie Sanders following him with 13% and 11%, respectively. In single digits are South Bend, Indiana, Mayor Pete Buttigieg with 6%, businessman Tom Steyer with 5%, businessman Andrew Yang with 4%, California Sen. Kamala Harris with 3%, and New Jersey Sen. Cory Booker with 2%. No other candidate receives above 1% in Quinnipiac's poll.

Steyer has now hit the polling threshold to qualify for the December debates, reaching above 4% in the Quinnipiac poll, his fourth. He still hasn't reached the fundraising threshold, so he isn't officially on the stage, with a few weeks left to qualify.

The University of North Florida poll, which is not a qualifying poll for debates, found similar results for the top few candidates, with Warren and Sanders at 10% each and Steyer at 8%.
