Who wrote the health care reform bill?

The Affordable Care Act of 2010 was actually written by a number of people, some of whom were in the House and Senate, but others of whom were advisers to President Obama (like Ezekiel J. Emmanuel); and some who advised individual members of congress (like Elizabeth Fowler). Other influences included lobbyists from the healthcare industry; the former governor of Massachusetts (and Republican presidential candidate) Mitt Romney; MIT Economics professor Jonathan Gruber (a former aid to Mr. Romney and later an adviser to the Obama Administration); and Harvard Professor of Public Health John McDonough (also a former adviser to Mr. Romney, and later an adviser to several US senators).
