Of the “approve”, they actually mean
“I approve of the self-righteousness I feel when I think about how much I care about providing affordable healthcare for everyone.”
I don’t doubt the existence of people like that but I believe most of this 37% is people who still think they are gonna get something free out of bammycare. Watch what happens as these leaches find out that their shiny new bammycare card won’t actually get them a free doctor, or possibly any doctor at all.
