2010 Maryland gubernatorial election
The 2010 Maryland gubernatorial election was held on November 2, 2010. The date included the election of the governor, lieutenant governor, and all members of the Maryland General Assembly. Incumbent Democratic Governor Martin O'Malley and Lieutenant Governor Anthony Brown won election to a second term in office, defeating Republican former Governor Bob Ehrlich and his running mate Mary Kane.
Ehrlich had previously lost to O'Malley in 2006. O'Malley and Brown became the first gubernatorial ticket in Maryland history to receive more than a million votes.
While Ehrlich won a clear majority of Maryland's counties, he lost in the area between Baltimore and Washington, which accounts for more than 90% of the state's population. This allowed O'Malley to win by a relatively large margin of 14.4%.
Background
In his first term as governor of Maryland, Martin O'Malley had made accomplishments, including raising total state tax collections by 14%. In April 2009 he signed the traffic speed camera enforcement law. He had supported raising revenue to try to overcome an imminent state deficit. Through his strenuous lobbying, he also implemented on a statewide level, Maryland StateStat One, the same CitiStat system he used to manage the city of Baltimore as mayor. One off his first actions as governor was to close the Maryland House of Corrections in Jessup, a notoriously violent maximum-security prison. By 2010, O'Malley's approval ratings had reached 55%, making his chances of reelection very good.Democratic primary
In the Democratic primary O'Malley faced J. P. Cusick and Ralph Jaffe, placing him in an unusual position, as he had run unopposed in the 2006 Democratic primary. He benefited from being the incumbent, and he handily defeated them in the primary. O'Malley received 86.3% of the vote. Cusick came in second with 9.7%, and Jaffe finished in last place with 5% of the vote. O'Malley again chose incumbent Democratic Lieutenant Governor Anthony Brown as his running mate.Candidates

The frontrunner for the Republican primary was former Republican Governor Bob Ehrlich. He faced Brian Murphy in the primary. Like O'Malley, Erlich had also run unopposed in the 2006 Republican primary. Ehrlich easily defeated Murphy in the Republican primary by a margin of 75.8%-24.2%. He chose his former Secretary of State Mary Kane as his running mate.Candidates
