The race in Maryland's newly drawn 6th Congressional District will begin to heat up this week. On Tuesday, Democratic State Sen. Rob Garagiola is expected to announce he will seek his party's nomination for the seat. He'll be looking to knock off incumbent Republican Rep. Roscoe Bartlett, who's held the 6th District seat since 1993.
The district saw the biggest changes under the new redistricting map that was passed by the General Assembly earlier this month. It now includes a large portion of Montgomery County, where there are no elected Republicans at any level.
One resident of the district has already sued, saying the new map dilutes agricultural-related voting concerns. But Gov. Martin O'Malley says the new district reflects the increasing population along the Interstate 270-corridor. Former Montgomery County Councilwoman Duchy Trachtenberg has said she will also seek the Democratic nomination, while four other Republicans will challenge Bartlett.
