In their final debate before they face Democratic primary voters, Hillary Clinton and Bernie Sanders traded sharp jabs on health care. Pundits focused on how the barbs would affect the horse race, whether Democrats should be bold and idealistic (Sanders) or shrewd and practical (Clinton), and how Sanders’ “Medicare for All” scheme would raise taxes by a cool $1.4 trillion. (Per. Year.) Almost no one noticed the obvious: the Clinton-Sanders spat shows that not even Democrats like the Affordable Care Act, and that the law remains very much in danger of repeal.
