Redistricting affects election outcomes by altering the boundaries of electoral districts, which can significantly influence representation and voting power. The process is often used strategically to favor a particular political party, a practice known as gerrymandering. By redrawing districts, legislators can manipulate demographics to create areas that lean towards their party, impacting electoral competitiveness. This shift in district lines can affect voter turnout, party affiliation, and ultimately the composition of legislative bodies, making redistricting a critical aspect of electoral politics and democracy.
