Black and Hispanic voters are deserting the Democratic party in numbers that will present a concern for Joe Biden’s re-election effort, a poll has found.

Among Black Americans expressing a party preference, the Democratic lead over Republicans has dropped by almost 20% in only three years, according to the Gallup survey.
