Edwards' truly universal health care plan will ensure that every American has health insurance. He will require proof of insurance when income taxes are paid and when health care is provided. Families without insurance will be enrolled in Medicare, Medicaid, SCHIP or another targeted plan or be assigned a plan within new Health Care Markets.

Families who lose coverage will be expected to enroll in another plan or be assigned one. For the few people who refuse to pay, the government will help collect back premiums with interest and collection costs by using tools like the ones it uses for student loans and taxes, including collection agencies and wage garnishment.

Edwards was actually pretty specific here on the penalty. In various news accounts in the pre primaries including the debates, he was less specific. I had not gone to the Edwards site until getting this for you.
