Interesting to see, but how significant is this? Or to say another way, does the faith of Catholic voters move them towards voting a certain way? It would appear not based on the splits we see here.

It's very significant. The Roman Catholic vote is roughly 20-25% of the electorate.

As I said above, more important would be adding other variables - not only location (as I said) but also demographics, income, education etc.

Things are very rarely that simple to buttonhole into one box.

"Jews" are not ultra-liberals, but those in the big cities tend to be (if the Pew polls restricted to Jews and Catholics in New York city, I'm sure those percentage numbers would be higher -- as would various non-Catholics as well)
