Catholic vote with a slight bias toward the liberals and Protestant vote with a slight bias toward the conservatives. But except for the Kennedy disaster. American Presidents have been all Protestants and the Protestant electorate is much larger, so the (for example) 45% Protestants that vote liberal are a bigger problem than 55% Catholics: they are more people.
Besides the country was set up by the Protestants. They therefore built in the liberal bias into the system. They wrote the Constitution; they voted for Protestant Roosevelt to create the New Deal and they voted for Protestant Johnson to cement the Great Society, America’s crippling welfare system. These two defections (over the course of three election cycles) of the Protestant electorate to the left were critical in the liberal slide of the 20th century. Now they should own the outcomes of their bad theology and unworkable social theories.
If you want to move the Catholic Church to the left, come join her. There is nothing that can possibly endear you to the Luther’s and Calvin’s theological fables, and you’ll be a part of true spiritual awakening of America rather than ones watching from the sidelines and tsk-tsking over things past.
You seem to have an agenda that isn’t conservative, a sort of tribal identity that trumps conservative politics, even an insulting view of America as getting better as it becomes leftist and foreign, as long as it is absorbed by Rome.
Judging by a 150 years of Catholic voting, that agenda explains why Catholics are a liberal voting block and why they are the power base of the left, as we have seen in California.
Since FR is a political site, you really should think more like a conservative, and less like someone who embraces the left as long as it can lead to America becoming Catholic.
