That's 100% opposite of the current state. Historically Democrats and Republicans used the classic gerrymandering.

However, now it's pretty much only Republicans who rely on computer-aided models to gerrymander the districts.

There _are_ Democratic examples, and the worst ones are in Maryland and Illinois. But they pale before the Republican gerrymandering.

It's true that both parties take part in it, however Democrats feel forced into it and would rather not. Democrats have repeatedly put forth efforts to end the practice. They have little choice but to play by the rules as they are until they manage to finally put a stop to it.
