If "what do you pray for?" is too personal for him, he shouldn't have run for office and pretended he was Christian or agree to do an interview on a (NO) Catholic network. This was a softball question he could have used to reaffirm his stance on abortion, his family, or just maybe talk about Jesus Christ directly, but he would never let that happen. It's a major weakness for him and all traditionalists know it even if they don't admit to it.
But since we're so locked in on separating our faith from our public lives, something as innocuous as a "what do you wish for?" question becomes off limits. This election was over before it began folks. Catholics don't "win" these sorts of things, we never did and we never will. Thank you JFK, Governor Cuomo and Justice Scalia for trailblazing the moral paralytic doctrine for RCs in public office!
