Last weekend, former President Barack Obama acknowledged a blunt political reality: “The average person doesn’t want to have to navigate around a tent city in the middle of downtown … and we’re not going to be able to generate support [for treatment] if we simply say, ‘It’s not their fault, they should be able to do whatever they want,’ because that’s a losing political strategy.”

What makes the remark notable is not merely its candor. It is the history behind it.
