I don't understand how that has any effect. Each congressional district varies in size and shape from time to time, because populations grow and move. A state that has more than one congressional district must redraw the districts when the population of one is significantly larger or smaller than the others. The party that rules that state, if there is only one, has the right to redraw the lines (constitutional right). All parties and independents run for congressional office for the same districts. Gerrymandering is the process of redrawing the boundaries on a congressional district (or legislative district) so the ruling party has an advantage. In other words, try to exclude all Dems from a district with a Pub congressman.

To affect gerrymandering, it is necessary to affect the perceived population of voters. They use voter addresses and voting history to redraw the lines. When a Pub thinks you vote republican because you registered republican, they will include you, if possible, in a district with a majority of Republicans. If you then vote any other way, except Republican, you have screwed with gerrymandering.

@EdEarl gerrymandering only works within the 2 party system. When you have nearly half the population registered, and or claiming to be independents, who most of don't vote,along with all others that feel their vote is useless, overwhelming the 2 party system with a collective vote if given a reason to get out and vote, you basically eradicate gerrymandering. If their system is based on registered republicans and democrats, which was at 26% each during the last election cycle, don't you have 48% of the population out of the system? I would imagine when broken down by state you'll get close to the same percentages? I know here in Ohio our supreme court just ruled they have to redraw the lines to a fairer manor. What ever that fucking can be LOL. I can't find any information stating whether registered independents or non affiliated voters are or are not a part of drawing lines though.

That's true
