After months of speculation, Bronx Borough President Adolfo Carrion Jr. will be leaving NYC for DC to take a position as the director of the White House Office on Urban Policy in the Obama administration. NY1 reports that the announcement will be made today: "The race to succeed Carrion will be decided in a special election in April." And Politicker NY forecasts, "The expected candidates are Assemblyman Ruben Diaz. Jr., who supported the new Democratic County Leader in a coup last year, and City Councilman Joel Rivera, whose father was ousted in that coup. (Other names talked about include City Council woman Helen Diane Foster.)"
