It all comes down to technology. In the good old days the pols didn't know quite so precisely what the implications of their district-line drawing would actually be. To go by the GA experience of the Democrats, tho, maybe the tech isn't what they thought it was! The thing about Gerrymandering is, tho, that the more seats you try to make for your people, the less safe you can make each one. Trying for 4 seats was greedy, they now wish they had settled for 3 safe seats and a sure loser.But there's no way to prevent the Gerrymander game. What criteria would you institute to prevent it? Only at-large voting would do it.
