Minority population would soar in GOP district under new map

The population of African Americans and Hispanics would grow by roughly 130 percent in the district represented by Republican Rep. Roscoe Bartlett, R-Md., under a new congressional map proposed by Maryland lawmakers.

The map threatens the safety of Bartlett — one of two Republican representatives in the eight-district state — by lopping off Republican-leaning counties from his Sixth Congressional District, including Frederick, Carroll and parts of Baltimore counties, while adding a hefty portion of the heavily Democratic Montgomery County.
