President Trump trails Democratic front-runner Joe Biden by 10 points among registered voters in a hypothetical 2020 match-up, according to a poll released Sunday.

Biden has 53 percent support in the Washington Post-ABC News poll, compared to Trump's 43 percent. Just 3 percent of respondents are undecided.

Biden enjoys support from independent voters and self-identified moderates, the Post noted, adding that the former vice president leads Trump by 7 points among independents and 28 points among moderates.

Trump in the new poll also lags behind Sen. Kamala Harris (D-Calif.) by 2 points, 48 percent to 46 percent, and Sen. Bernie Sanders (I-Vt.) by 1 point, 49 percent to 48 percent.

Pollsters found the president tied with Sen. Elizabeth Warren (D-Mass.) and South Bend, Ind. Mayor Pete Buttigieg (D).

Trump, however, leads a generic "Democratic candidate who you regard as a socialist" by 6 points, 49 percent to 43 percent.

Americans listed the economy, health care and immigration as the top issues, pollsters found, followed by foreign policy, gun violence, taxes, issues of special concern to women and abortion.

The poll of 875 registered voters, conducted June 28 to July 1, has a margin of error of 4 percentage points.

The RealClearPolitics index of national polling shows Biden with an 11-point lead over the Democratic field. Harris is in second place, followed closely by Sanders and Warren.

Biden has faced withering criticism for his recent remarks about his ability to work with segregationists during his time as a senator.

On Saturday, he apologized, maintaining he had done the right thing by working across the aisle with people whose views he found "repugnant" but apologizing if he gave the impression he was praising the senators.
