"After a million dollars in Van Hollen ads, Donna emerges with the base of support required to win the Democratic nomination for U.S. Senate, with substantial leads among women, African Americans, and in Prince George's County and the critical population center in Baltimore City," Edwards spokesman Benjamin Gerdes said in a statement. "In Donna, Maryland families have a champion who will fight every day to ensure equal pay, end gun violence, and take on the Washington special interests holding middle class families back."
