A survey released Tuesday finds former Vice President Joe Biden has a commanding lead over Democratic presidential candidates in Mississippi.

Half of likely Democratic primary voters favor Biden, according to a Millsaps College/Chism Strategies survey.

The survey asked Mississippi Democrats which of the 24 party hopefuls they were supporting or leaning toward.

Only three other candidates — Senators Elizabeth Warren, Bernie Sanders and Kamala Harris — polled above 5 percent, the survey found, and about 21 percent of respondents were undecided.

The survey found strong support for Biden among black Democrats, who are expected to make up about three-fourths of the Democratic electorate in 2020.

According to the survey, 58 percent of African American Democrats found Biden favorable.

The survey took place a few days after Biden recalled a time a "civility" in the U.S. Senate. The former Senator from Vermont said he could get along with anybody, specifically mentioning the late Mississippi Sen. James O. Eastland, a segregationist.

Eastland had a long history of racist remarks, including that black Americans belonged to an "inferior race," and Biden's remarks drew swift rebuke from some Democrats.

Only 29 percent of white Democrats favor Biden, with 18 percent for Warren, 11 percent for South Bend, Indiana, Mayor Pete Buttigieg, and 10 percent for Sanders.
