Ad campaigns aim at health overhaul

Major business groups are launching a series of new advertising campaigns aimed at shaping Congress' health overhaul. The U.S. Chamber of Commerce, for example, plans to introduce a sharply worded multimedia advertising campaign pushing back against the key planks of Democrats' health overhaul proposals. America's Health Insurance Plans, the nation's largest health insurance lobby, has also launched a television advertising campaign costing at least $1 million, with ads that say the industry supports the idea of health overhaul.
