Some of the maps proposed by the Ohio GOP this year (and rejected as unconstitutional by the Ohio Supreme Court) are close to this. I believe I read an estimate that the dems would need to average 70-30 statewide to control half the seats.
It went to a federal court who ruled the districts not fair but will let them stand for the 2022 elections.
The GOP ignored the rule of law, ignored the courts, and ran out the clock. They will cement their hold on the state in 2022.
