Liberal group invokes history in health reform push

A key liberal group released an ad Tuesday encouraging lawmakers to support health reform, likening the vote to support for historic social programs.

A new 30-second television spot from the group Americans United for Change pushes lawmakers do weather any controversy over the health proposals before Congress and cast a vote in favor of the reforms.

The ad notes controversy over Social Security, child labor laws, and national parks when those were authorized by Congress, suggesting that the new health rules would become a core part of American culture like those programs.
