COLUMBIA, S.C. (AP) — President Joe Biden is spending the weekend in South Carolina, intent on driving home two messages: He’s loyal to the state that saved his campaign in 2020 and he’s determined to win back Black voters here and elsewhere who were central to his election last time but are less enthused this go-round. Biden will be the keynote speaker Saturday night at the state party’s fundraising dinner ahead of its first ever “first-in-the-nation” Democratic primary on Feb. 3. He’ll stick around to attend a political event at St. John Baptist Church on Sunday, in a state where politics and faith are intertwined.
