Missourians seem to know how to pick a winner. The presidential candidate who has won Missouri in a general election has gone on to take the White House in every election (bar one, in 1956) since 1900.

Although the state is not as delegate-rich as California or New York, the biggest prizes in the “Super Tuesday” contest, former first lady Hillary Clinton and Barack Obama are in an intense fight for a primary win. Victory in Missouri would not only add to the candidates' crucial delegate count, it would also be valuable symbolically: proof that a candidate can score a win in a state that acts as a bellwether for the nation.
