In 1994, a series of political ads starring the fictional couple "Harry and Louise" helped sour the public's view of President Bill Clinton's plan for universal health coverage. Now, Harry and Louise are back asking the presidential contenders to make healthcare their top domestic priority. The latest Harry and Louise ads will run during the Democratic and Republican Party conventions. The groups sponsoring the new ad include the National Federation of Independent Business, Families USA, the American Cancer Society Cancer Action Network, and trade groups for hospitals.
