Partisan gerrymandering to increase the power of a political party has been practiced since the beginning of the United States. Maryland's 3rd congressional district (represented by John Sarbanes, a Democrat) is currently among the most gerrymandered districts in the US.
2. Both Republicans and Democrats gerrymander. Illinois's 17th congressional district (repped by Democrat Jesús "Chuy" García ) was gerrymandered: major urban centers are anchored and Decatur is included, although nearly isolated from the main district. It was redrawn in 2013.
3. In 2006, SCOTUS held that the 23rd congressional district in Texas was racially gerrymandered in violation of 1965 Voting Rights Act, to protect a Hispanic Republican who later lost to a Democratic challenger in a run-off after a Federal District Court redrew the district.
