2012 United States House of Representatives elections in Maryland
The 2012 United States House of Representatives elections in Maryland were held on Tuesday, November 6, 2012 to elect the eight U.S. representatives from the state of Maryland, one from each of the state's eight congressional districts. The elections coincided with the elections of other federal and state offices, including the quadrennial presidential election and an election to the U.S. Senate. The new congressional map, drawn and passed by the Democratic-controlled Maryland General Assembly, was signed into law by Governor Martin O'Malley on October 20, 2011. The map made  the 6th district, at that time represented by Republican Roscoe Bartlett, much more favorable to Democrats. District 1. The redrawn 1st district includes Caroline, Cecil, Dorchester, Kent, Queen Anne's, Somerset, Talbot, Wicomico, and Worcester counties, as well as parts of Baltimore, Carroll, and Harford counties. Republican Andy Harris, who had been elected in 2010, was re-elected by a wide margin against Democrat Wendy Rosen. Muir Boda, an asset protection manager, ran as the Libertarian nominee. Democratic primary. Rosen won the primary, however, she withdrew from the race on September 10, 2012, after evidence surfaced that she'd voted  in both Maryland and Florida in the 2006 and 2008 elections. Rosen had property in Florida, and Maryland law allowed property owners to vote in local elections even if they live elsewhere. However, her Florida voting registration reportedly also gave her access to state and federal elections there, something which was not allowed by Maryland law. As the deadline for replacing a candidate on the general election ballot was August 28, members of the Democratic Central Committees of each county in the district had to choose a write-in candidate to run in November. Two potential candidates who indicated an  interest were former U.S. Representative Wayne Gilchrest, who represented the 1st district as a Republican from 1991 to 2009, and LaFerla, who finished a close second in the primary. LaFerla was then endorsed as the Democratic write-in candidate. District 2. The redrawn 2nd district includes parts of Anne Arundel, Baltimore, Harford, and Howard counties, and parts of the city of Baltimore.
