Campaign to make insulin affordable in the US

The documentary Pay or Die describes the campaign to make insulin affordable in the US.

The campaign passed a law in Minnesota to provide inexpensive insulin to some of the people who need it. The article is not clear; in particular, I can't tell whether the law prevents the usual gouging or only has the state subsidize the gouging.

If we are thinking about how to broader problem of providing all Americans with the medical treatment they need, that detail makes a big difference.
