The Missouri bellwether was a political phenomenon that noted that the state of Missouri voted for the winner in all but one U.S. presidential election from 1904 to 2004 (the exception being 1956). While states like Pennsylvania, Nevada, Florida and Wisconsin have been arguably stronger indicators of political trends in recent years, Missouri was a consistent swing state throughout the 20th century. Prior to the 2008 elections, Lincoln County, Missouri was said to be the only bellwether county in a bellwether state. Missouri was also considered a bellwether of U.S. views on hot-button social issues such as stem cell research and school vouchers. Some economists also considered the state a bellwether for economic trends such as consumer confidence and unemployment. Political history From 1904 to 2004, Missouri's electoral votes always went to the winner of the presidential race, with only one exception: in 1956, during the landslide re-election of President Dwight Eisenhower, Missouri went to Illinois Governor Adlai Stevenson. The state's accuracy in voting with the national consensus includes the highly competitive elections of 1960, 1976, and 2000. In 2006, Missouri's bellwether status gained renewed attention because of the 2006 Senate race between incumbent Republican Senator Jim Talent and Democratic State Auditor Claire McCaskill, which was considered vital to which party controls Congress. Additionally, Missouri had a ballot measure, Missouri Amendment Two, regarding stem cell research that drew national attention as an indicator of mainstream sentiment towards this controversial issue. On Election Day 2006, both McCaskill and Amendment 2 narrowly received majority support among Missouri voters. The victories of McCaskill and five other Democratic colleagues allowed their party to regain power in the U.S. Senate. Missouri was again the center of much media attention in 2012, after Rep. Todd Akin (R, MO-2) made controversial remarks regarding what he called "legitimate rape." McCaskill was seen as one of the most vulnerable Democratic incumbents prior to these remarks, but went on to win the 2012 election by nearly 16 points. In the 2008 presidential primaries, the state voted for the major parties candidates who went on to secure their parties' nominations: John McCain (Republican) and Barack Obama (Democratic). Missouri did the same in 2016, voting for Hillary Clinton by a razor thin margin in the Democratic primary—actually tying with her opponent Bernie Sanders in one county—and voting narrowly for Donald Trump in the Republican primary.
