It's about damn time that the Democratic Party figure out that you fight Republicans by going lower when they go low. It's why, even if I don't particularly like Gavin Newsom, I appreciate that he's at least apparently prepared to gerrymander the entire GOP out of California if Texas does their redistricting fuckery. It's about 10 years past the time at which Democrats need to stop living and playing by rules and norms that ceased existing the moment that Trump came down his golden elevator.
If Republicans are so opposed to gerrymandering, maybe they could- wait for it- bring an anti-gerrymandering bill before the Congress which they control fully!
