There was an increase in humanist Catholic voters in this survey based on this survey under discussion.
There was not an increase in white humanist Catholic base (the number of white catholics taking the survey) - whites are a constant or diminishing base in this Nation.
Given white humanist catholics are not breeding at a large rate or flooding over the borders, the increase was logically from immigration from Central and South America where the Catholic base population increased.
That would probably be those Catholics from South and Central America. They have a long history of faith mixed with power stuggles with the Church so I am not surprised to see them do the opposite of what the church tells them to do when it comes to power.
