I suppose it is not really "news" that the group Catholic Democrats has decided to come out swinging against former Sen. Rick Santorum. In a press release yesterday, the group said Santorum "had among the worst voting records in the US Congress on issues related to the Catholic social justice tradition and the family, despite his efforts to portray himself as a 'pro-family' Catholic who is concerned about poverty."
Catholic Democrats looked at Santorum's ratings from both the Catholic social justice group NETWORK and the Children's Defense Fund, and found his rankings were lower than even most other Republicans. Graphs of the rankings can be found here.
