Americans are partly to blame for political partisanship . Redistricting is only part of the reason why communities are divided . People moving into areas with like minded peers , refusing to share opposing views complicates issue . A number of states , many of them in the South , with a history of racially discriminatory voting practices , also must get pre-clearance from the Department of Justice before tweaking their voting laws and maps . This political sorting then trickles up to differences in who we elect and policies they support .
