Sherrill also received plenty of support from big-name Democrats.
Former Vice President Joe Biden, leading a rally for Sherrill in September, said her candidacy could be crucial in helping Democrats win control of the House.
“We desperately need, in both parties, men and women of character,” Biden added. “Mikie gets it.”
