So what explains the 1/3 of states where the Democrats benefit from Gerrymandering. Is it because they have little choice but to game the system to win?
Both sides do it. Both sides are guilty. The complaint is that the GOP is better at it, not that they are the only ones. I will grant you, though, that the GOP’s success has allowed it to remain more conservative than would be the case if they needed more centrist votes.
