You need to notify the political world and the Vatican, and, and convince them that you are the defining authority for who gets counted as Catholic in election studies.
Also you can give them your new total for the Catholic population in the US.
Do we get to include all of the bitter ex-Catholics who currently describe themselves as Evangelicals, OPC'ers, Mormons, Buddhists, etc. or just those too lazy or intellectually dishonest to recalibrate their self-identifications?
