Make gerrymandering of districts illegal. The only criteria that voting districts should be based upon is geographical location. Current redistricting policies only serve to disenfranchise voters of both parties, decrease the effectiveness of our democratic process, and encourage partisan divisions.
End Gerrymandering. One of the causes of our do-nothing congress is that well more than three-quarters of all US House districts are considered "safe" seats for their party. This is due to redistricting boundaries which are drawn in order to "stack, pack and crack" voters in their districts. Enforce that all districts be drawn to follow municipal boundaries as closely as possible, and otherwise be as square as possible.
End gerrymandering. This issue is currently governed by a maze of legislative and judicial actions; it may require a constitutional amendment to make reform stick. Require that all districts have approximately equal populations, be geographically compact, and not deliberately be designed to favor or disfavor any particular group.
Add a section to the Voting Rights Act, which provides that all voters are entitled to districts which have not been gerrymandered. Then define the term: a district is gerrymandered if there are more than 12 edges in its border, or if the square of the district perimeter exceeds 20 times the area of the district
