Biden leads the nomination race with the backing of 31 percent of Democratic primary voters, followed by Elizabeth Warren at 21 percent, Bernie Sanders at 19 percent, and Pete Buttigieg at 7 percent. In early October, Biden was at 32 percent, Warren 22, Sanders 17, and Buttigieg 4…

“If Hillary Clinton were to enter the race, she’d likely do so near the top of the pack,” says Democratic pollster Chris Anderson, who conducts the Fox News Poll with Republican Daron Shaw. “And Michelle Obama could probably clear the field.”

Twenty-seven percent of Democratic primary voters would definitely vote for Clinton, including one-third of those backing Biden and one-quarter supporting Warren.

The numbers are rosier for former first lady Michelle Obama: 50 percent would definitely vote for her, including nearly 5 in 10 of Biden’s and 4 in 10 of Warren’s supporters.
