"Why don't we teach statistics in high school? It is easier and a lot more useful than calculus."  There is an AP course in Statistics and I would bet that most Jesuit high schools offer such a course.  To properly understand continuous variables, such as the normal distribution, you actually do need calculus.  Regarding the two courses as complementary, rather than in opposition, may be the rational approach.

There is today no such thing as a "Catholic vote".  There is a "Latino Catholic vote" and a "white Catholic vote" and the two are very different.  White Catholics vote like other white people.  Latino Catholics vote like other Latinos.  Ethnic identity seems a much more accurate predictor of voting behavior than does Catholicity.
