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.
As long as you are interested in facts, Mainline Protestant does not include evangelicals. Ir means Episcopal, Presbyterians, Methodist, and northern Baptist. Only Southern Baptists tend to support conservative causes.
