From a report at the link below:
The federal government spent more on broken state-run exchanges than it did on its own troubled system.
Of the 14 states, plus the District of Columbia, that established their own health insurance coverage under Obamacare, seven remain dysfunctional, disabled, or severely underperforming.
Development of those exchanges was funded heavily by the federal government through a series of grants that totaled more than $1.2 billion—almost double the $677 million cost of development for the federal exchange.
The report goes on to list problems for each of the states: Oregon, Maryland, Massachusetts, Vermont, Nevada and Hawaii.
Some of these exchanges may end up being repaired before Obamacare's open enrollment window ends in March. Others may eventually choose to link up with the federal exchange system.
Given the scope of the technical turmoil, it's unlikely that all of the problems in all the of the exchanges will be fixed very soon.
This means that as Obamacare moves forward, its performance will at best be spotty, with technical troubles that will be resolved in some places, but ongoing in others.
