Racism vs. Sexism

If you vote McCain you're a racist...but if you vote for Obama, doesn't that make you a sexist?

From NYT's Article:

If Mr. McCain wins Pennsylvania, it would keep him alive and scramble the picture for Mr. Obama. And it would lead to grave pronouncements about racism and the so-called Bradley effect of whites not being honest about their preferences to pollsters. Surveys of voters leaving the polls in the April primary found that 19 percent said race played an important role in their decision (as they delivered the state to Senator Hillary Rodham Clinton by nine percentage points over Mr. Obama).
