Gerrymandering is destroying America(n democracy)

[A Black Falcon]

So for a bit more on gerrymandering, had Ossoff been so lucky as to win, how long could Democrats have actually held the seat for?

I would say 2022, because after the 2020 election the Georgia Republicans (presuming they are still in power, which they almost certainly will be) will redo the electoral map, and redo the gerrymander so that things won't be as close next time. As a Georgia Republican said, that district is a gerrymandered seat and it is not supposed to be competitive... and they will do what they can to make things go back to that, because that's what Republicans particularly do, they push for every possible advantage they can no matter how undemocratic it is. (And I say 'Republicans' because Democrats very rarely come even close to being as aggressive about gerrymandering as Republicans do.)
