Henry Cabot Lodge gave us Vietnam as much as Kennedy did. He was the one who gave the go ahead for the murder of the Diem brothers. Catholics voted for Eisenhower in 1956, and McCarthy was a Catholic. Some Catholics are liberal. Most mainstream Protestant bodies are liberal.
Too much effort for me, when you start saying that the president did not get us into his war, then you are doing what is so common on these threads and among salesmen, you want to weave a tale, sell a narrative in an effort to overcome the actual facts.
The voting graph in post 62 tells a gruesome tale, and mainline Protestant are still voting Republican, and to the right of Catholics.
Think 2008 and Obama.
