This is a dangerous move, and shows very like movement off of the monstrosity they have proposed. I trust most people will see right through it.
The legislation that sets up and defines the "co-ops" will have details, just like the current disaster has, I presume.
Watch for Obama and his flying-monkey supporters to lash out at middle America after this. If you wake up one morning and notice a brand new section-8 slum apartment building at the end of your suburban street, you'll know how it got there.
It doesn't need details. Even a vague hint will suffice for the subsequent creation of a mountain of regulations to implement the will Congress purportedly evinced.
Obama and the left know this.
