As did the pharmaceutical industry and the AARP. Even though the individual members of all, on the whole, will be negatively effected by Obamacare. But the government made them (the industry groups) an offer they couldn't refuse. AARP stands to make BILLIONS from "supplemental insurance" they'll broker to their members. The pharmaceutical industry seems to have received certain "guarantees" from the government, what they are, we don't know yet, nor do the companies really know if the government will keep its promises. Same with the AMA.
All have made Faustian bargains for their own selfish reasons, and they just have to hope they'll be the last eaten by the crocodiles they're feeding.

From my best information, Big Pharma companies tend to have bipartisan boards of directors and they switch political gears at the drop of a hat.
