Benny, there is no bipartisan backlash to gerrymandering. The backlash is only coming from partisan Democrats. The Supreme Court of the United States has recently clearly upheld the legality of gerrymandering.
The system isn’t any more broken today than it was 60 years ago. The only difference is that 60 years ago the Democrat Party controlled most redistricting, especially in the South, and gerrymandered districts to their great benefit. That lasted many decades. Today, since about ten years ago, Republicans reversed that and gained the same control of redistricting that Democrats used to have. Democrats, of course, hate that. So they now decided it has become anti-democratic — since they are no longer in charge. It was good, though, while they ran the ship.
It may be true that today, due to micro level data on election districts by the block level and using sophisticated software algorithms gerrymandering can be done much “better” than could be done 20+ years ago. But it wasn’t due to Democrats lacking effort while they were in control to gerrymander to the most of their ability decades ago.
So it is the Democrats loss. They’ll have to live under this new regime. Not because I said so, but because the Supreme Court has so ruled.
