As has been seen from the breakdown of data from the most recent catastro - uh,... election - Catholics are about where the country is, as a group, neither particularly liberal nor particularly conservative. 51% of the country voted for the anti-Christ, about 48% for Gov. Romney. 50% of Catholics voted for the anti-Christ, about 48% for Gov. Romney.
However, like the rest of the country, the real story is when you break things out by race and by religious practice. As you well know, non-Hispanic white Catholics voted fairly solidly for Gov. Romney. As well, weekly-Mass-going Catholics also voted solidly for Gov. Romney.
Just as with minority Protestants, minority Catholics voted very strongly for the anti-Christ.
If you want to gauge the Catholic vote, it's more valuable to look at ethnicity and religious practice first than to look at bare religious identification. Just like the rest of America.
As pointed out by others, Catholic voters aren't a monolithic voting bloc anymore, or anything even approaching.

The Catholic denomination supports the democrat party.
America’s second largest denomination, the Southern Baptists are about an 80% republican vote.
Protestants as a whole have only gone democrat 3 times in history, the last time was in 1964, Catholics have only voted republican 5 or 6 times, and only once against a democrat incumbent. The Catholic vote is pretty much where it has always been.
