If the Roman Catholic Church has the right to exclude women from the fullness of sacramental inclusion because of her genitals then why can't a man who claims the right to grab women by the genitals become President of the United States. 
The Roman Catholic Church claims to be the one, true, holy representative of Christ on earth
The United States of America claims to be the greatest nation ever on the face of the same earth.
One can "blame" the Pope or the President-elect but that is mere scape-goating for the main reason. There are two options: a) God, b) you and I.
