Just more than three-quarters of the vote has been reported in Chesterfield County, Va., an important suburban and exurban region southwest of Richmond. In the tally so far, Mitt Romney leads President Obama 54 percent to 45 percent. If those percentages hold, Mr. Romney’s performance there would match almost exactly Senator John McCain’s margin of victory in Chesterfield County in 2008: 53 percent to 46 percent. Former President George W. Bush, however, when he carried the state in 2004, won Chesterfield County with 63 percent of the vote. — Micah Cohen
