Health Care For America Now, a coalition of groups pushing for health care reform including a public option, announced a $1 million television ad buy attacking the insurance industry Thursday.

Before this buy, the coalition had already spent $7 million this year on advertising, according to the coalition's spokeswoman, Jacki Schechner.

The coalition consists of some of the top-spending groups involved in the health care debate, like the AFL-CIO, the American Federation of State, County and Municipal Employees, the SEIU and the American Academy of Family Physicians.

The ad contrasts an image of UnitedHealth CEO Stephen Hemsley's home with an image of a foreclosed home. "If the insurance companies win, you lose," the ad concludes. "We need good health care we can afford with the choice of a public health insurance option."

The ad will air for two weeks nationally on MSNBC and on local channels in four targeted markets: Washington, D.C., Philadelphia, Maine and Minneapolis.
