Those states that were stupid enough to spent hundreds of millions of dollars to setup their own "exchange" are going to shut them down so fast it'll make a Washington Bureaucrat's head spin.
Why would any state at this point, continue to incur the expense of running an exchange when the USSC just said the subsidies were available to all states that didn't have an exchange?
This thing may collapse under its own weight yet.
The state exchanges will all fold up like a cheap suitcase. Of those 13 remaining most are dysfunctional and a drain on state budgets. The US tax payer paid 4.2 billion to set these up. Money down a rat hole.
