The survey results show a surge for Biden since he launched his presidential campaign last week. A Harvard CAPS/Harris Poll survey from March pegged his support in the primary field at 35 percent, though at the time he hadn’t yet entered the race.

The poll results are largely in line with other surveys conducted in recent days that show Biden widening his lead in the sprawling Democratic primary field.

MORE in the 2020 general election, Biden still has a significant lead, with 40 percent of respondents saying as such. Sanders comes in after the former vice president at 13 percent.

But according to the poll, voters are looking for more than just someone who can defeat Trump. Thirty percent said it was more important to nominate a candidate who shares their positions on the issues, while 26 percent said that the ability to beat Trump was a more important quality in the eventual Democratic nominee.

The Harvard CAPS/Harris Poll online survey of 1,536 registered voters was conducted from April 30-May 1. Of that, 259 self-identified Democratic voters were asked about their candidate preference in the party’s primary field.

The Harvard CAPS/Harris Poll is a collaboration of the Center for American Political Studies at Harvard University and The Harris Poll. The Hill will work with Harvard CAPS/Harris Poll throughout 2019.

Full poll results will be posted online later this week. The Harvard CAPS/Harris Poll survey is an online sample drawn from the Harris Panel and weighted to reflect known demographics. As a representative online sample, it does not report a probability confidence interval.
