Almost all these people are additions to the Medicaid rolls or heavily subsidized. Republicans had a plan which would have covered these people without taking over the entire health care system.
In Washington state the numbers were, 1/3 into expanded Medicaid, 1/3 eligible for traditional Medicaid (but were too dumb to apply), 1/3 bought a policy through the exchange. The number of people actually buying insurance that had lost their old policies was never released.
