Poll: Sanders leads 2020 Democratic field with 28 percent, followed by Warren and Biden

Sen. Bernie Sanders (I-Vt.) led the Democratic field in a Sunday CBS News-YouGov poll that also saw Sen. Elizabeth Warren (D-Mass.) rise to second place following a strong debate performance last week.

Sanders led with 28 percent, followed by Warren with 19 percent, former Vice President Joe Biden with 17 percent and former New York City Mayor Michael Bloomberg with 13 percent. Former South Bend, Ind., Mayor Pete Buttigieg and Sen. Amy Klobuchar (D-Minn.) rounded out the field with 10 percent and 5 percent, respectively.

Fifty percent of respondents said they found Warren the most impressive candidate at last week’s debate in Las Vegas, where she took aim at Bloomberg’s history of sexist remarks in the first debate for which the former mayor qualified.

The poll also showed Sanders performing best against President Trump in a head-to-head match-up, at 47 percent to 44 percent, followed by Biden, with 47 percent to 45 percent and Warren with 46 percent to 45 percent. Buttigieg and Trump were tied in a head-to-head match-up at 44 percent each, while the president led Klobuchar 45 percent to 44 percent and Bloomberg 45 percent to 42 percent.

However, the poll also found that 65 percent of voters expect Trump to be reelected.

The poll was conducted Feb. 20 to Feb. 22 among 10,000 registered voters, including 6,498 Democrats and independents planning to vote in the Democratic primary. The full sample has a 1.2 percentage point margin of error, while the sample of likely Democratic primary voters has a 1.7 percentage point margin of error.
