From Politico:
…prediction that Obamacare’s employer mandate would — and perhaps should — be jettisoned shocked Democrats back in April.By July, the former aide and longtime confidant of President Barack Obama had a lot more company. More and more liberal activists and policy experts who help shape Democratic thinking on health care have concluded that penalizing businesses if they don’t offer health insurance is an unnecessary element of the Affordable Care Act that may do more harm than good.
The article could be summarized this way: Opponents were right all along about the employer mandate and its effects, and Democrats now realize that, too.
