Perhaps this will be the catalyst and certainly, many more Catholics are talking about this now and are angry. But, I'm not confident.
Moreover, Catholics, as would many others, may have a difficult time voting for a Mormon.
Catholics are two voting blocs in these US. One bloc is those for whom “Catholic” describes a faith and a religion which they believe and practice, and which forms the basis of their way of life. These vote primarily for Republicans. The other bloc is those for whom “Catholic” is a secularized cultural identity. They were baptized as children, but do not believe the faith, nor practice the religion, nor allow it to have any particular influence over their lives. These primarily vote for Democrats.
