Surprise, surprise, there was plenty of politics involved.
With the federal government taking over a large share of the health care business through the new Affordable Care Act exchanges, providers such as CVS need to be in regulators' good books. CVS's drug business is at the mercy of regulators from the Food and Drug Administration, the Center for Medicare and Medicaid Services, and numerous other agencies within the Department of Health and Human Services and elsewhere.
The company is taking no chances that it could fall out of government's favor. CVS spent $13 million on lobbying in 2013, according to the Center for Responsive Politics, over 17 times as much as the firm spent in 2007.
