"Critics of the law have outspent supporters $204,038,930 to $57,902,790," CMAG noted in a report. "Four hundred ten advertisers have aired 1,018 individual creatives mentioning the plan in a negative way; 48 advertisers have aired 90 creatives mentioning the plan in a positive way," it added. "The highest-spending proponent of the law by far, accounting for 65% of all pro-law ad spending, has been the Department of Health and Human Services." HHS has spent $11.2 million on TV advertising.
Supporters spent the largest share of their budget on national network and cable ads. Opponents, which included individual GOP politicians and various special-interest groups, "spent their largest share in markets covering potential presidential swing states, including two markets based in Pennsylvania and two in Florida, plus markets in Colorado, Arizona, Georgia, Nevada and Ohio."
The biggest single spender among opponents has been the U.S. Chamber of Commerce, which spent $6.3 million on general-information ads, as well as on ads in House and Senate races targeting those who supported the bill and backing those who opposed it.
