PRINCE WILLIAM COUNTY, Va. — The Prince William County Electoral Board thought they had enough voting machines. Last night they admitted they didn’t, and that led to voters at Woodbridge’s River Oaks precinct waiting in lines for up to four hours to cast their ballot Election Day Nov. 6. The last ballot was marked at River Oaks at 10:45 p.m., marking it the most problematic of the county’s 84 77 voting precincts.
