I would go further. Republicans should have taken the administration to court to force the ACA be implemented as written, with no delays or exemptions. Force the Democrats to testify under oath, with threat of perjury, to defend why some organizations have been exempted; was there a "quid pro quo" for this decision?
And why allow the administration more time to implement the ACA by delaying the employer contribution?
Force the implementation and speed up the implosion.
