Nope. Putting the exchange implementation issues squarely on the shoulders of the executive branch. HHS and CMS/CCIO have acted horribly, arrogantly and incompetently.
I certainly fully fault the Rs for their stupidity in their constant defunding rhetoric and silly votes. But, they have no impact on the setting up the federal exchanges. They (HHS) are in complete control of the implementation and need little to no legislative action to set up the marketplace or the federal hub.
Now, states can complain...NC certainly acted poorly in not accepting set up funds. BUT, they defer to the feds for the FFE set up. Its all on them. And its a mess. The states issues are more on the support side and thus will send folks to DC for assistance. But again, little to do with the mechanics of the set up.
Its certainly easy to say a lot of things have gone "well", the giveaways and rule changes. These were largely mandates to the insurers and employers and required the fed to do little other than set the rules (which they consistently do late, but thats a different story).. But anything the feds have had control over has been full of issues (Long term care, employer mandate reporting, SHOP, the individual marketplace to name a few).
I deal with the exchange each and every day. My life would be much easier (and more profitable) if it worked well. And its a total mess. All smoke and mirrors. And it didn't have to be.
