California was re-districted by Commission in the 1990s. Back then, the Republicans briefly held a majority in the State Assembly, and had a split in the US House delegation. In 2000, the Dems did the re-districting, and they now enjoy a nearly 2/3rds advantage.
The fact is, this so-called bipartisan commission coming to Ohio is going to be controlled by Dems, regardless of who the governor, auditor, secretary of state, etc. is.
In fact, the Ohio Dems are so inept that this commission will do a better job for them than they could do for themselves if they had actually gone out and won the necessary elections (2 out of 3 of Gov, Sec of State and Auditor) to control our apportionment board.
