Gerrymandering still requires significant popular support. In a two party system it can drop things to at minimum 25% vs 50% support in theory, but in practice it’s hard to maintain below 40%.

Don't worry, that's where voting suppression tactics under the guises of "security and fraud prevention" come in.

This is how apartheid systems perpetuate while still ostensibly offering supposed universal suffrage

Jerrymandering has significant popular support, it’s just that it’s one-sided. In a two-party system, it’s incredibly easy to maintain that support. Just look at voter suppression, it’s as one-sided as possible, yet gaining a lot of ground in a lot of states.

That’s just defeatist nonsense. Texas has turned ridiculously blue in under a decade. Almost feels like your defeatism has an agenda.

Blue? There is nothing blue about Texas’s recent policy. Austin and Houston got bluer, everywhere else got redder.

I wouldn’t call a 3.5% win, in Texas of all places, a tendency towards trending blue. You seem to be ignoring where most of the population in Texas is based.
