Why don't both sides admit that the practice of extreme gerrymanders can backfire later in the decade as much as it succeeds in the first election out of the box?
How often does a gerrymander actually backfire? What we saw in Georgia in '02, While GA's map didn't achieve what the Dems wanted (and was overturned), Dems still have 3 more seats than they did going into redistricting (6D-7R) vs (3D-8R). That said, I still don't think that extreme gerrymanders are a good idea. Also, esp. with Dem gerrymanders in conservative states, it results in a very conservative Republican delegation (GA's GOP delegation are perhaps the most conservative in the nation).
