One-third of Democrats and Democratic-leaning independents polled selected Biden as their choice to take on President Trump in 2020, The Hill reported.
Other popular choices included Sen. Bernie Sanders (I-Vt.) with 13 percent and Sen. Kamala Harris (D-Calif.) at 9 percent.
Democratic Sens. Elizabeth Warren (Mass.) and Cory Booker (N.J.) were also possible candidates.
Biden has consistently polled ahead of other Democrats and Trump in a number of surveys about potential 2020 showdowns.
But the former VP has not yet said whether he plans to run, saying last week that he is not running for president “at this point.”
The CNN poll also found that 46 percent of Americans say they think Trump will win reelection, a six-point increase from when the same question was asked in March. Another 47 percent think he will not win a second term.
The poll was conducted from October 4 to 7 among 1,009 adults. It has a margin of error of 3.8 percentage points.
