And temporary allies. Maybe with more than two parties we could move past the idea that the platform of one party has to be the exact opposite of the other on every issue. Then, maybe, not every effort would result in a gridlock. Perhaps a nice side effect could be that people stop seeing others who disagree with them as evil.
It's hard to make progress with temporary allies. They're going to expect some kind of mutual benefit. That is easiest when you've got trust, and the belief that you will have my back in the future. It's hard to have faith in temporary allies, and less opportunity to make compromises and trade-offs.
It's far easier when your allies are long term. Which functions a lot like a single party even if you don't call it that.
