When running for office, Belloc had a slightly different view than JFK on the effect of his religion on his politics:
HB: My religion is of course of greater moment to me by far than my politics, or than any other interest could be, and if I had to choose between two policies, one of which would certainly injure my religion and the other as certainly advance it, I would not for a moment hesitate between the two.
JFK: Whatever issue may come before me as President--on birth control, divorce, censorship, gambling or any other subject--I will make my decision in accordance with these views, in accordance with what my conscience tells me to be the national interest, and without regard to outside religious pressures or dictates. And no power or threat of punishment could cause me to decide otherwise.
Ahhhhhh...Mister we could use a man like
