If you haven't come across the political debates on Catholic sites you're missing some interesting debates.
I cam across something this morning that I'd missed the first time I tried to research the - attributed to William Buckley but actually coined by Garry Wills - epigram, "Mater Si, Magristra No" in the July 29, 1961 issue of "National Review."
Some time previously - not sure if it was 1961 or a few years earlier - one of the Popes had issued an encyclical on Catholic social teaching, which struck Buckley as having socialist leanings.

Buckley authored what is described as a short statement - not the column by the same name that many people think he authoried - to the effect that the socialist teaching of the Pope "must strike many as a venture in triviality coming at this time in history."
By which Buckley later clarified he meant that capitalism was such a success in so many countries; and communism was a menace around the world. He may have also gone on to say (since I didn't take really good notes as to attribution) that Catholics didn't need to pay any attention to the Pope on social issues when they enter the voting booth in the United States. He also did clarify that Catholics could differ as to the effects of a particular economic policy. Buckley's posture was basically a defense of capitalism.
The article also cited Robert Bork's opinion.
"Chaput (Denver's current Bishop?) himself has said Catholics have 'listened to the world too politely when it lies' about 'the death penalty, or our obligations to the poor, or the rights of undocumented workers, or the real meaning of pluralism, or our international responsibilities.'"
The debate still rages 45 years later.
