Are the lines drawn by majority vote? If so, the rats get to write whatever boundaries they want. If this is the case, what will happen is the computer guys for the rats will give the D’s on the committee a plan. The D’s will trade some favors and ask the computer guys to make some adjustments to favor the guys that gave them the favors. The computer guys redo it. Then they call a vote.
If they have to get one R vote to pass a plan, then something fairly balanced should come out of the process. But if it’s majority vote, this doesn’t seem like something activists should spend a lot of time on.
Luckily we can make some of it back in North Carolina, Indiana, Missouri, Wisconsin, and Arizona.
