Dear Mr. Santorum:
Not only does the University of California system have American History courses, contrary to your claim to a crowd in Wisconsin, they require American History in order to obtain an undergraduate degree. Now, admittedly, all campuses except UC Santa Barbara allow students to take this in high school, but all campuses except for UC San Francisco have actual American History courses. This could possibly be because UCSF is a medical institution. They have classes in nursing, dentistry, and biomedical engineering instead. Not to mention a medical school.
You might try to lie instead about something that cannot be disproved by a five-minute Google search.* At least give those of us who live in the reality-based world a run for our money.
