Mr. McCain backs legislation sponsored by Arizona Rep. John Shadegg. Known as the Health Care Choice Act, it would allow individuals living in one state to purchase health insurance being sold to people living in other states. The policy would still have to meet the regulations of the state in which it is being sold, and would be subject to additional federal oversight.
In other words, the McCain-Shadegg reform would allow a person living in New Jersey or New York to buy health insurance that is being sold in and regulated by Pennsylvania or Connecticut. That's hardly the Wild West of health insurance.
About 18 million Americans today buy health insurance in the individual market because they don't have access to employer coverage or they aren't in a government-sponsored program (Medicare, Medicaid, etc.).
