The role of race and gender in the 2020 presidential race - CBS News poll

In the 14 states holding primaries on Super Tuesday, CBS News' Battleground Tracker poll finds Joe Biden atop the field. African-Americans make up a larger share of Democratic voters in these states than in Iowa and New Hampshire — the states holding the earliest contests.

Biden continues to lead among black Democrats by an overwhelming margin: 50% pick him as their first choice, far ahead of Bernie Sanders (15%) and Elizabeth Warren (14%). Moreover, black voters who back Biden say their support is strong. Pete Buttigieg continues to struggle with black voters, at just 2% in the Super Tuesday states.

Nine in 10 black Democrats think it's very important that the Democratic nominee understand blacks' needs and problems.
