ABC, NBC refuse to air ad critical of Obamacare

"The ABC Television Network has a long-standing policy that we do not sell time for advertising that presents a partisan position on a controversial public issue," spokeswoman Susan Sewell said in a written statement. "Just to be clear, this is a policy for the entire network, not just ABC News."

NBC, meanwhile, said it has not turned down the ad and will reconsider it with some revisions.

"We have not rejected the ad," spokeswoman Liz Fischer told FOXNews.com. "We have communicated with the media agency about some factual claims that require additional substantiation. As always, we are happy to reconsider the ad once these issues are addressed."

Adams objects to ABC's assertion that his group's position is partisan.

"It's a position that we would argue a vast majority of Americans stand behind," he said. "Obviously, it's a message that ABC and the Obama administration haven't received yet."

Dick Morris, a FOX News political analyst and the League of American Voters' chief strategist, conceptualized the advertisement and said its purpose was to "refocus" the debate on health care reform.

"I feel the whole debate on health care reform needed to be refocused on the issue of Medicare," he told FOXNews.com. "Most of the debate had been on issues of socialized medicine and cost. I felt that the impact of the legislation in cutting the Medicare program and enforcing rationing needed to be addressed."
