COLUMBIA, S.C. (AP) — Joe Biden said Sunday he can "unite this country, the whole country" after scoring a comeback victory in South Carolina's Democratic primary that could force moderate rivals out of the race and blunt the rise of progressive leader Bernie Sanders.
Biden vowed he would improve his campaign operation, his fundraising haul — and even his own performance — as the race pushes toward Super Tuesday, making the case he is the candidate that can win up and down the ballot and in states beyond those voting next week.
"I feel good," Biden said on ABC's "This Week." "I can win and I can bring along Democratic victories."
