From almost the instant last fall that Republicans knew they'd be taking total control of government, the repeal of the Affordable Care Act, the Holy Grail they'd been questing for since the law's passage seven years ago, was finally within their grasp. And yet, from the moment they took power, the realities of governing ran headlong into the necessities of campaigning as they grappled with the negative polling associated with forcibly ripping healthcare away from millions of people. That's generally an unpopular position. This in turn might explain why we're not really hearing about Obamacare repeal much these days, and when we do, it's as a, "Yeah, we'll get there eventually" can being kicked down the curb. Why the switch? Jonathan Chait has some thoughts.
