Hispanics are a major subgroup of the Catholic population and I doubt that significant numbers of this subgroup will vote Romney. Also, in a number of regions many Catholics are also union members who have always voted democrat.
A lot of the Hispanics who vote will be voting for Romney in this election, especially in Florida. Our weakest group here are actually the older Irish American transplants from the Northeast, who will vote solidly Obama, no matter what the bishops say. I haven’t quite figured out what religion they’re practicing, anyway. They go to mass, but they seem to believe nothing that the Church teaches, especially in the moral sphere.
Ohio, for example. Esp, in the NE.
