Poll: Overwhelming majority of black voters back any 2020 Democrat over Trump

An overwhelming majority of black voters — 85 percent — said in a new Hill-HarrisX poll that they would choose any Democratic presidential candidate over President TrumpDonald John TrumpGOP senators balk at lengthy impeachment trial Warren goes local in race to build 2020 movement 2020 Democrats make play for veterans' votes MORE.

The survey, which was released on Monday, found this sentiment to be particularly true among black voters along partisan lines.

Ninety-eight percent of black voters who identify as Democrat, and 72 percent of those who identify as independent said they would back whoever ultimately becomes the Democratic nominee over Trump. Just 12 percent of black voters who identify as Republican said the same. 

Black voters are considered a key voting bloc with the Democratic Party, particularly in states like South Carolina where they make up a significant proportion of the electorate.

According to a Fox News poll that came out on Sunday, Biden leads the Democratic field by 29 percentage points in the Palmetto State with 41 percent support. This marks a 6-point increase from July.

Biden’s sizable lead is largely attributed to his support among black voters in the state.

But recent polling suggests Warren’s overall support is on the rise among this key demographic.

A Quinnipiac poll released earlier this month found that Warren's support among black voters ticked up to 19 percent, a 9-point increase since August.

The Hill-HarrisX survey was conducted among 210 black voters between Sept. 18 and Sept. 23. The margin of error of this poll is plus or minus 6.8 percentage points.
