Yesterday, according to the exit polls, between 53 and 54% of American Catholic voters cast their ballots for Barack Obama, despite the Democratic candidate’s enthusiastic support for unrestricted legal abortion.
Nationwide, Protestant voters supported John McCain, by a solid 54- 45% margin. But the Catholic vote broke for Obama. Why? ...
The support that Obama won among Catholic voters is noteworthy because in the last presidential contest, in 2004, President Bush won 52% of the Catholic vote while his opponent John Kerry— himself a Catholic!— managed only 46%.
“But the Catholic vote broke for Obama. Why?”
I think because the Hispanic vote was heavily for Obama, by almost 2-to-1. White Catholics voted for McCain, though I have no idea what margin they delivered.
If Catholics voted like Mormons, Jersey, MI, OH, PA, and RI would be GOP strongholds. Many Catholic immigrants (Italia, Polish, Irish) have worked blue collar jobs and have a family history of befriending labor unions. As a result, American Catholics have an economic populist streak. Also, Protestants oppose abortion more strongly than Catholics.
