WINONA, MO—After learning about the importance of zinc mining to residents in the crucial swing state of Missouri, presidential candidates John McCain and Barack Obama both expressed their irritation Monday over being forced to adopt a position on the issue in order to please voters. "I'll tell you what I think about zinc mining—I don't," an exasperated Obama told reporters, adding that he would reluctantly research the subject after finishing the "million other things" he had to do. "What's McCain's stance on it? I guess I'll be for it, unless he's for it, in which case I'll be against it. Either way I don't care." McCain had an identical reaction when informed that he would have to take a stance on health care, the economy, and education.
