The group is rallying support in favor of a public health care option, something they say 76% of Americans support and insurance companies oppose. Sen. Baucus is leading reform on the Senate Finance Committee and has yet to include a public option. The ad lists contributions the democratic senator has received from insurance companies and health care professionals.

In response to the ad Baucus' press secretary Tyler Matsdorf says, "As Senator Baucus continues to work to pass meaningful health care reform that lowers costs and improves quality, he is looking at all options and is only driven by one thing: what is right for Montana and the country. He will continue working together with the President, his colleagues in Congress and groups and individuals from across Montana and the nation on a bill that can ensure quality care, lower costs and pass the Senate."

The ad starts airing in Billings, Butte, Bozeman and Helena Wednesday and lasts one week, unless more funding is raised for more airtime.
