So legal with restrictions is a middle ground, but there is a ton of debate and tactical voting within that middle ground.
- Sometimes the controversy is about the process, such as historical efforts for suffrage for women.
- Sometimes 90% vote benefits for themselves at the expense of 10%. Most unbalanced budgets fall in this category.
- Sometimes 10% people preserve benefits for themselves at the expense of everyone else.
Especially concerning about automatically hiding debates without consensus is that it hides things that are important or urgent but haven't reached consensus (yet).
Maybe there are other mechanisms to provide transparency there, but the article did not seem to describe any.
In isolation you can find many examples of this. But, political alliances mean that group may be trading financial support for support of another issue. Farm subsidies and net neutrality could be traded with people voting for both even if they only care for one or the other.
It smells like corruption, but political horse trading does represent people caring more or less about different issues.
Consider three friends going out, one cares a lot about the movie they watch, another cares about what they eat for dinner, and the third really wants to go out to a specific club afterwards. If everyone votes on each activity separately then people may be less happy than a compromise.
Zooming out a bit, a less cynical take (merely observation) is that we seek what we think are the right means for our goals (and these too diverge a lot).
Maybe I want money, maybe you'd rather have love of the people; maybe we just both wanna make this world better, maybe we're mostly in it for ourselves.
The point is, industrious types seek the means to industry, romantic ones seek an emotional path to/of success, technical minds seek the knowledge or practice of their puzzle, etc.; and in the end everything is just as it should/cloud/would have been. There's a reason you asked 100%, got 75 and I let you walk away with it. However I'd want to spin it, it just had not mattered to me as much as it had to you.
Consider, (53+25) = 78% of the US population believes Abortion should be legal in some or all situations. That’s why a total ban is rarely debated it’s a campaign issue, but making it illegal would quickly cost elections.
Restrictions on the other hand also have popular support (53 + 21) = 74%. Thus rather than a ban one party pushing for more restrictions. This is not a failure to achieve a ban, but rather a middle ground with significant popular support.
