Gerrymandering is the practice of drawing district lines to unfairly favor particular politicians or political parties in elections. It is a political dirty trick—and an extremely harmful one—that turns democracy upside down, letting politicians choose their voters instead of voters choosing their politicians. Gerrymandering allows politicians to get reelected even if they fail to address the problems that the majority of the public wants them to solve. That failure has consequences for every issue that Americans care about, including efforts to expand health care and to protect Americans from gun violence—two issues that the Center for American Progress has written about at length. It also has very real and harmful consequences for some of the most vulnerable Americans: children.
