There is a reason no one would put a fox in charge of guarding a henhouse. Politicians have a fundamental conflict of interest when it comes to redistricting: they have a personal stake in having the boundaries drawn to increase their chance of winning. Experience shows that no matter how carefully we try to direct them, politicians will find creative ways to manipulate requirements, standards, and guidelines to their benefit. Independent commissions don't have a bias toward any political power. This could explain why they are becoming so popular with the millions of voter who are tired of extreme partisanship.
