THE BURNED OVER DISTRICT

Because the Affordable Care Act has made the health insurers into allies of President Obama and the Republican/Teabaggers into enemies of business and the free marketplace.

Those same insurers have long viewed government as an unreliable business partner that imposed taxes, fees and countless regulations and had the power to cut payment rates and cap profit margins.

But since the Affordable Care Act was enacted in 2010, the relationship between the Obama administration and insurers has evolved into a powerful, mutually beneficial partnership that has been a boon to the nation’s largest private health plans and led to a profitable surge in their Medicaid enrollment.

The insurers in turn have provided crucial support to Mr. Obama in court battles over the health care law, including a case now before the Supreme Court challenging the federal subsidies paid to insurance companies on behalf of low- and moderate-income consumers. Last fall, a unit of one of the nation’s largest insurers, UnitedHealth Group, helped the administration repair the HealthCare.gov website after it crashed in the opening days of enrollment.

“Insurers and the government have developed a symbiotic relationship, nurtured by tens of billions of dollars that flow from the federal Treasury to insurers each year,” said Michael F. Cannon, director of health policy studies at the libertarian Cato Institute.

The relationship is expected only to deepen as the two sides grow more intertwined.

“These companies all look at government programs as growth markets,” said Michael J. Tuffin, former executive vice president of America’s Health Insurance Plans, the main lobby for the industry. “There will be nearly $2 trillion of subsidized coverage through insurance exchanges and Medicaid over the next 10 years. These are pragmatic companies. They will follow the customer.”

And in the meantime, the Republican/Teabaggers are left holding their teeny, weeny peenies and opposing free enterprise.
