After winning the passage of OBRA–93 and the ratification of NAFTA in 1993, the President made health care his major area of legislative focus in 1994. Though many corporations supported Clinton's health care proposal in hopes of reducing their own costs, several other groups strongly objected to the plan. Liberals criticized Clinton for not proposing more far-reaching reforms, while conservatives attacked the expansion of government. Interest groups ran ad campaigns alleging that the Clinton health care bill would lead to health care rationing, reduced choices, and increased costs. The Health Insurance Association of America's "Harry and Louise" ad campaign proved especially important in influencing the public against the Clinton health care bill. Meanwhile, Congressmen Newt Gingrich and columnist Bill Kristol convinced congressional Republicans to resist any form of compromise. Clinton's decision not to engage congressional Democrats and moderate Republicans early in 1993, and his own refusal to compromise on various aspects of the bill, further damaged any hope of passing a major health care bill. With Republicans unified against his plan, and with his own party divided, Clinton decided to abandon health care reform in September 1994.
