The actual goal is to make as many districts that are roughly 55-60% "theirs", just enough to ensure consistent wins, and then pack the remaining voters that are "not theirs" into as few districts as possible that contain 90% or above "not theirs" districts.
Along with that you also want the 'enemy' incumbents to live in one of your safe districts so they have no chance of getting re-elected. At the same time, the enemy's safe district has to run a new politician that will not be as influential as their predecessor.
If you want to actually try out the redistricting process, there is an online game to help out.
