WASHINGTON (AP) — Voters in the nation's capital are deciding whether Mayor Vincent Gray should get a second term amid a federal investigation of his 2010 campaign.
The Board of Elections says polls have opened Tuesday with no problems reported.
Gray faces seven challengers in the Democratic mayoral primary, and polls have shown him neck-and-neck with D.C. Councilmember Muriel Bowser. She says the city needs a fresh start as the mayor faces possible indictment.
Five people involved with Gray's 2010 campaign have pleaded guilty to felonies. Three weeks ago, federal prosecutors said for the first time that Gray knew about an illegal, $668,000 slush fund that helped him get elected. The mayor has denied wrongdoing and hasn't been charged.
Gray hopes for high turnout in less affluent areas where he remains popular.
