It turns out the Republican Party has relied on and cited "policy analysis" from a "research firm" that is wholly owned by a health insurance giant:
The political battle over health-care reform is waged largely with numbers, and few number-crunchers have shaped the debate as much as the Lewin Group, a consulting firm whose research has been widely cited by opponents of a public insurance option.
To Rep. Eric Cantor of Virginia, the House Republican whip, it is "the nonpartisan Lewin Group." To Republicans on the House Ways and Means Committee, it is an "independent research firm." To Sen. Orrin Hatch of Utah, the second-ranking Republican on the pivotal Finance Committee, it is "well known as one of the most nonpartisan groups in the country."
Generally left unsaid amid all the citations is that the Lewin Group is wholly owned by UnitedHealth Group, one of the nation's largest insurers.
So there you have it: the Republican Party and the health insurance industry. Throw in a Kent Conrad or two, and pretty soon you've got the circle of corruption, defined.
