A coalition of progressive U.S. faith groups and pastors has launched a push for affordable health care reform, an effort they say is rooted in a "scriptural call to act."OBAMA/Radio ads will appear from today until July 4th in five states: Arkansas, Colorado, Louisiana, Nebraska and North Carolina. The ads urge those states' Senators, whose votes could ultimately decide the fate of President Barack Obama's drive to transform America's health care system, to back legislation "that makes quality coverage truly affordable for every American family." You can see the ad script and audio here.Organizers also say that more than 600 clergy from 41 states and 39 denominations have said they will deliver sermons in coming weeks on the issue and urge their flocks to act. A pastors' guide to health care will also be distributed to 4,250 religious leaders along with a shorter version to wider church members.PICO National Network, Faith in Public Life, Faithful America, Sojourners, and Catholics in Alliance for the Common Good are the main religious advocacy groups behind the campaign.If this all sounds familiar, it should. The tactics being adopted by these liberal and centrist groups and activists are a carbon copy of the successful ones employed in the past by the U.S. religious right. The distribution of pastors' guides, the call for public policy to be guided by scripture (in this case compassion for the poor and the ill), the preaching of sermons on looming legislation -- it's all taken from the loose network of conservative Christians which has delivered many a vote for the Republican Party.Conservative Christians remain a key base for the Republicans and they have also been decrying "Obama-care" on talk radio, the blogosphere and other outlets.Photo credit: REUTERS/Larry Downing.  Members of the audience shake hands with U.S. President Barack Obama after his speech about reforming America's health care system in Green Bay, Wisconsin, June 11, 2009.
