Why the state is significant:
Missourians had a nearly perfect record of predicting the general election winner from 1904 to 2004, getting it wrong just once -- in 1956 -- when they backed Adlai Stevenson over Dwight Eisenhower.
Despite voting Republican in the last four presidential elections since 2000, the Bellwether State is considered a general election swing state.
In 2008, John McCain defeated Barack Obama by a razor-thin margin, 49.4 percent to 49.3 percent in Missouri.
In 2012, voter turnout in the Republican primary decreased more than 50 percent, slumping from 588,000 in 2008 to 252,000 four years ago.
