The rules don’t change.

1. Vote the party who stands the best chance on delivering a net-positive platform, even if it’s the best of a bad bunch.
2. Repeat.

It’s like evolution: with enough iterations, we will grow a good administration.

This means that we vote in the party we do, not because they’re good, but because these disenfranchising liars and racists and sellouts are the least-worse.
