Hours before Virginia voters head to the polls, the NAACP will go to federal court to demand that more voting machines be placed in minority polling places. A hearing in federal court is set for 3:15 this afternoon after the organization renewed its motion Friday to redistribute voting machines, extend voting hours and make paper ballots available in some precincts. The National Association for the Advancement of Colored People sued last week alleging the state was unprepared for Tuesday’s huge turnout in the presidential election. The group withdrew the request Thursday after mediation with state officials. NAACP officials said they didn’t expect any new hearing before the election. But NAACP President Ben Jealous said the organization concluded Friday the problems still existed.
