Last weeks Iowa caucuses marked the official beginning of the 2020 primary season. Democratic voters, however, remain as uncertain as ever about how things will end, according to a new HuffPost/YouGov survey .

In the poll, taken last Wednesday through Friday, just 5% of Democratic and Democratic-leaning voters say its clear whos likely to win the nomination. Another 47% say its down to just a few candidates, and 37% that its still anyones race.

One-quarter of Democratic and Democratic-leaning voters say they think former vice president Joe Biden is most likely to win the nomination, 24% that Vermont Sen. Bernie Sanders is, and about a third that one of the other candidates will. Another 18% arent sure.

Thats a notable change from late January , when about four in 10 believed Biden was most likely to win, putting him significantly ahead of Sanders.
