Gerrymandering is a practice intended to establish a political advantage for a particular party or group by manipulating district boundaries.
It is abused by both major political parties in the U.S.
Currently the U.S. Supreme Court is trying to decide if the practice is constitutional.
Maryland’s 3rd Congressional District has been described as the most egregious case of gerrymandering in the nation.
WUSA9 toured the district to document some of the curious effects. For instance, parts of the district are only three-blocks wide. In one case, a single neighborhood in Baltimore is represented by three members of Congress.
Critics say the district is drawn with the intention of dividing Republican strongholds to dilute their power, while connecting together far flung Democratic areas to create a safe seat in the U.S. House of Representatives.
Maryland's Democratic majority in the House of Representatives is 7 to 1. However, the statewide majority over Republicans is 2 to 1.
Nationally, electoral experts say gerrymandering in Republican held states favors Republicans in Congress.
