While I think the electoral map thingie posted doesn't look right, I'm going to remind everyone that the GOP don't need to gerrymander to be competitive.

If US elections would move to a more sane electoral system, what would happen is not permanent Democratic rule, but instead the GOP would instantly change their policies to be competitive in a new environment. There's a reason why in a two party system the parties tend to stay about 50/50; whenever the world changes, the parties change with them.

In other words, the point of gerrymandering isn't just to keep the GOP in power, it's just as much about protecting the current politics of the GOP and making it as immune as possible from democratic influence.
