Harry and Louise are back

Harry and Louise are coming back to television screens across the country to talk about overhauling health care. This time, they've switched sides.

TV ads featuring the fictional couple played a big role in derailing President Bill Clinton's effort to revamp the medical system in the 1990s. Back then, actors Louise Caire Clark and Harry Johnson played a middle-class couple worrying about the changes, and the ads were sponsored by the insurance industry, which was fighting Clinton's plan.

Now, they will appear in a $4 million TV campaign supporting a reshaping of health care, sponsored by Families USA, which champions affordable health care for families, and the Pharmaceutical Research and Manufacturers of America. The two groups, often at odds, have joined forces this year to support some general principles behind revamping health care, such as making it more affordable for low-income people.
