Just to give some context on how numbers can be misleading, a 40 / 60 split is only 10 away from 50; however, even though that 10% margin is small, in reality it that means there are 50% more people in favor of something.

For every 40 people that don't want something, 60 people do.

For every 4 people that don't want something, 6 people do.

For every 2 people that don't want something, 3 people do.

3 divided by 2 is 1.5, or 150%.

So, in this 56.6% versus 43.4% split, 30.4% more people are in favor of this bill.

But percentages are still weird. So even my example can be misleading. It's all about how you interpret it. For instance, a 95 / 5 split would mean 19x as many people want one outcome. So the gap is 90% in the ratio, but 1800% more people are in the 95 camp. (1800% more implies 1800% over 100%, so 1900% total, or just 5 x 19)

Another way to look at the data of the 43/56 split.

If 10,000 people are against it, then 13,040 people are for it.

If 10,000 people are for it, then 6,960 people are against it.

Numbers are tricky like that
