The Democrat party is not perfectly aligned with any particular church of course, no party is, but it best represents Catholicism and that is why it shares much of their agenda for America and the vote of it’s members.
Obama won 54% of the Catholic vote because he reflects their politics and goals for what they believe we should change into, a fight to change America that has been going on for more than a century.
That is completely false. Obama got 19 million Catholic votes from a population of over 68 million. That is 27%, not 54%.
You ought to be more concerned about the 50 million non-Catholic votes cast for Obama than trying to mischaracterize the 50 million Catholic votes he did not receive.
