LOL an independent commission drew that? Look at that Salt Lake District.
Yeah, independent commissions are actually pretty sh**tty. If you want reasonable maps, the only way to reliably get that is to remove the
incentive to gerrymander.
There will always be an incentive to gerrymander in a first past the post district-based system. That incentive can only be removed if you remove the connection between partisan outcomes and district shapes.
Switch to a different electoral system such as a mixed member proportional system, where only some members of Congress are elected in districts, and the remainder are elected in leveling seats which ensure that the final partisan outcome is always proportional to the popular vote. With an electoral system along those lines, nobody would care about the district lines since they would have no partisan effects, and the only thing with a partisan effect on control of the legislature would be the overall votes of the people. Consequently, whoever was in charge of drawing lines would simply draw reasonable compact districts.
But as long as we remain hitched to a first past the post system, the problem of gerrymandering will remain.
