Federal Court Strikes Down "Unconstitutional" Gerrymandering in North Carolina

[hazard]

I understand that there's an independent commission that draws the electoral district boundaries in Arizona and a few other states. What's stopping the bureaucrats in other states from following suit?

The legislature.

The authority to draw the electoral district boundaries lies, by law, with the elected state legislature. Which has an incentive in drawing districts that keep them in power by direct election.

To be honest, if the Democrats were better at it we'd be complaining about them, they've done it themselves as well.
