Here is an important "political" question for you (I say that in snark mode): When dealing with Catholics in the Republican Party, is their faith only worth mentioning when it is part of (a) references to their strange, culturally speaking, beliefs on issues of moral theology or (b) when they clash with good, progressive Catholics who are on the other side of the political aisle?
I certainly agree that it is fair game to ask GOP Catholics questions about how their faith influences their views on, let's say, the death penalty, immigration and health care. I say that because I think it's important -- for the same doctrinal reasons (see the Pope Francis address to the U.S. Congress) -- to keep asking Catholics in the Democratic Party obvious questions such as abortion, euthanasia and religious liberty. Oh, and the death penalty, as well.
It's a worldview thing, you see. Catholicism is a massive force in the lives of people who actually try to live it out and that would certainly be true when you are talking about the life of a political leader.
This would be true to ask faith questions if one was writing about a relatively young Catholic father who is trying to make a career choice that would almost certainly pull him away from his family more than the political post that he already holds.
Let's say, for example, that this young father is trying to decide whether to become Speaker of the House.
Now, run an online search for the terms "Paul Ryan" and "Catholic" and you will get all kinds of things.
