Answer: D. Only white Protestants should be president.
Al Smith was an American politician who was the Governor of New York four times. He was also the Democratic Party's candidate for President in 1928.
Smith was the son of an Irish-American mother, and was raised as a Catholic. He was the first Catholic candidate for president, and this allowed him to mobilize the "Catholic vote." However, he received staunch opposition from white Conservative Democrats in the South, particularly from Southern Baptists and Lutheran Germans.
