Michael New’s latest on the claims of Catholics in Alliance for the Common Good is a must read:
An August 2008 study released by the group Catholics in Alliance for the Common Good had Obama supporters (and some editorial boards) swooning. Analyzing state level abortion data from 1982 to 2000, it purportedly found evidence that increased spending on various welfare programs resulted in substantial reductions in state abortion rates. The spin given to the results was that many pro-life laws, such as those requiring parental notification for abortions performed on minor girls, had little effect. So the paradoxical message to pro-life voters was that they could best advance their interests by electing pro-choice Democrats instead of pro-life Republicans.Not surprisingly, this study had a substantial impact on the debate over sanctity of life issues during the 2008 Presidential election. Self proclaimed pro-lifers who support Democratic Presidential nominees can be found in every election cycle. However, this study gave Doug Kmiec, Nicholas Cafardi, and others intellectual legitimacy in arguing that pro-life voters should vote for liberals, even if they favor abortion-on-demand and its public funding, in order to advance the pro-life cause. At last, there was a methodologically sophisticated study which allegedly demonstrated that the welfare policies favored by Democrats were more effective in preventing abortion than the pro-life laws supported by Republicans. It seemed too good to be true.
It was. In November, with no public announcement, Catholics in Alliance for the Common Good removed this study from their website. A replacement version was uploaded shortly thereafter. The replacement version differs from its predecessor in a number of interesting ways.
