Advertising wars escalate in healthcare fight

The type of advertising war that helped doom the last effort to overhaul the nation's healthcare system is heating up. Business groups opposed to healthcare bills floated by House and Senate Democrats launched print ads, and the Republican National Committee ran its own TV ad as well. Until now, ads for and against President Obama's proposed healthcare overhaul have been run by lesser-known groups. Interested groups are stepping up their efforts during Congress' July Fourth recess.
