I hope that it is changing though. First, it has gotten to the point when more people recognize that they faith was gradually stolen from them and they learn to resist it.
Second, we have more courageous priests and religious, and lay apologists who educate the public. Mother Angelica with EWTN, Father Fessio with Ignatius Press, Karl Keating and his Catholic Answers Live and catholic.com have become leaders of American Catholic revival. That cannot be reversed.
Thirdly we have the Internet. I am convinced that through efforts of countless bloggers and through unimpeded access to the Holy Scripture and the works of the Fathers of the Church the foundational lies of Protestantism will be exposed. Soon the day will come when no one will be taking seriously Protestant claims of adherence to the Word of God, and with that, Catholic Church will be one clear choice for anyone interested in the teaching of Jesus Christ.
Will it be culturally more Latino-Pole-Italian-Bavarian etc.? Probably not. The assimilation process is in the American fabric; we recently notice the Latinos because the left-wing cultural regime stopped assisting people who assimilate. But like water cannot run uphill, so americanization of the Latino is inevitable. The people around me in the pews are all, perhaps, Schmidts who style themselves Smiths, but they are all American. There are distinctly immigrant churches, -- I lovingly remember one in Sacramento that was Vietnamese-Hispanic at about 80%, but the cusp of New American Catholic movement will be educated and white, and mainstream.
The Catholic vote won’t change, it will continue as it has historically, the majority of the Catholic denomination’s members will continue to support the democrat party.
A Happy 2015 to you - enjoy your blessings and may God grant you many more.
