Obamacare was supposed to provide unicorns and rainbows: How can it possibly be hurting companies and killing jobs? Surely there's some sort of Republican conspiracy going on here!
"This became apparent when various large businesses responded to the enactment of Obamacare by taking accounting steps to reflect tax changes brought about by the new health care legislation. The additional costs created by Obamacare, conveniently enough, weren't going to strike until later, after the November elections.
