Before 2010, a number of Democratic states, including California, implemented independent redistricting commissions and the likes in order to prevent gerrymanders.
In 2010, the Republicans took a number of state legislatures, and were then able to use the every-10-years redistricting to gerrymander their way into permanent power and increase their share of seats in the the federal House of Representatives.
This has meant that further anti-gerrymandering measures in Democratic-leaning states would give the Republicans permanent control over one branch of the Federal government, so Democratic-leaning states adopted a no-unilateral-disarmament policy, where they're no longer passing measures like that at the state level, but regularly try to pass a federal anti-gerrymandering law, which would eliminate it nationally. To date, none of those attempts has gotten past a Republican filibuster in the Senate.
