The US Democratic party has a national policy of non-gerrymandering at all levels of government. Maryland had a Democratic gerrymander in the 00s, but it was exchanged for a fair map in 2011.
The US Republican party, on the other hand, has a national policy of gerrymandering as much as possible. The national committee hired gerrymandering consultant Thomas Hofeller to draw Republican-maximizing maps for every state in 2009, and used those maps as the backbone of their REDMAP plan to seize permanent control of every state through extreme gerrymandering.
Similar to how only companies with an ethics hotline get ethics complaints.

They’ve tried to take it to multiple courts that have all found it unconstitutional. They are still trying to hold elections with it.
They were, in a very real sense, the people who instituted the independent commission. A commission that deadlocked itself before the state legislature decided it failed and they needed to draw the lines.
Had they not voluntarily limited their own power, there would be no legal case at all.
I think the solution is really, really easy. Treat politicians like kids.
One gets to draw the lines, but they have to draw several different versions, that are at least XX% different, in terms of voter groupings. Then the other gets to pick which one gets used.
And when they can't get along, I get to send them to the naughty step.
