Not everyone follows the rule. I remember one year when I guy from Spokane or somewhere equally western cast his vote opposite what everyone else on the state did, simply because he could. It has probably been 20 years or more since that event (and something similar may happen more often for all I know). The electoral college is damned annoying. When you really think about it, the federal government is just humoring all of us by letting us vote at all, because they really don't have to pay any attention to the popular vote if they don't want to.
