Now that the ACA is on the books, and the private-insurance options are on shaky ground, there’s no real reason for proponents of the ACA not to fully embrace the public option. It’s what most of them wanted all along, and the turbulence among the private insurers provides the perfect excuse to pursue it.

The fact that introducing a public option at this stage would only add to the instability of the private options offered on the exchanges is not a reason for the public-option advocates to abandon the idea because they never really wanted a functioning private-insurance marketplace anyway. The goal all along has been government-run health care, even if they haven’t always been willing to admit that.
