ATLANTA (AP) — Raphael Warnock is the first Black U.S. senator from Georgia, having broken the color barrier with a special election victory in January 2021. Now Warnock can add another distinction by winning a full six-year term in a Tuesday runoff. Standing in the way is another Black man, Republican challenger Herschel Walker. The two men have cut different paths and offer clearly opposing visions for the country, including on race and racism, despite their common upbringings in the wake of the civil rights movement and the guarantee of a historical first from their Senate matchup. Black voters in this Deep South state say the choice is stark.
