Missouri may be the ultimate bellwether state. The Show Me State has failed to pick the president only once since 1904. The lone exception was 1956, when Missouri sided with Democrat Adlai Stevenson but the nation chose Republican Dwight Eisenhower.
With those odds, it makes the race in Missouri, which is in a statistical dead heat, even more intriguing. As the quintessential battleground state, the region's current political atmosphere may explain the tightness in the polls.
