"Duncan said that he planned to stay on as Montgomery County executive but said he would not seek re-election for that office.
His withdrawal comes eight months into a campaign during which he cast himself as a proponent of education and a more mature alternative to Gov. Robert L. Ehrlich Jr. and Baltimore Mayor Martin O'Malley.
The announcement virtually guarantees that O'Malley will capture the Democratic nomination in the Sept. 12 primary. Many Democrats expressed concern that a contentious primary battle would leave the party's nominee vulnerable and cash-depleted going into a general election against Ehrlich, who is expected to raise $20 million for his re-election effort."
