I read an interesting post on the NY Times site this morning, which said:
Analyzing data from the 2008 American National Election Study, we found no relationship between negative feelings toward African-Americans and opposition to government-provided health care among whites without college degrees. For college-educated whites, however, negative racial feelings were strongly associated with increased opposition to such reform. As the graph below shows, for whites without college degrees, feelings toward African-Americans are unrelated to whether respondents support or oppose government-provided health care. For college-educated whites, however, increases in negative feelings are associated with large increases in opposition to government-provided health care.
They must be right; they have a graph!
