Nov 10 (Reuters) - U.S. President Joe Biden's re-election campaign on Friday will register for the South Carolina Democratic primary, the party's first official clash and an early enthusiasm test for a president dogged by a rash of recent polls that show declining support among Black voters. It will mark a return to a state that Biden credits with catapulting him to the White House. Biden ousted Iowa and New Hampshire from the top spots on the party's nominating calendar in favor of South Carolina. James Clyburn, a South Carolina congressman and one of the nation's most influential Black leaders, is filing on behalf of the Biden campaign. A CNN poll published on Oct. 31 found that Biden's overall approval rating in South Carolina was just 33%, lower than his national approval, which has hovered around 40% in most polls.
