This week’s stunning delay in the Affordable Care Act’s (ACA) employer mandate was hardly the first time that ObamaCare’s implementation effort has stumbled, as the president’s signature domestic policy initiative has suffered several self-inflicted wounds on the path toward full implementation.

Democrats say the law will work well once it’s fully implemented, and President Obama has acknowledged that there will be more “glitches and bumps” as key provisions start to take effect.

While many of the administration’s challenges stem from entrenched Republican opposition to anything that would help the law function better, plenty of the bumps in the road so far have also arisen from the law itself.
