Context paragraphs:
United States presidential election, 1972: The United States presidential election of 1972, the 47th quadrennial presidential election was held on Tuesday, November 7, 1972.  The Democratic Party’s nomination was eventually won by Senator George McGovern of South Dakota, who ran an anti-war campaign against Republican incumbent President Richard Nixon, but was handicapped by his outsider status, limited support from his own party, the perception of many voters that he was a left-wing extremist and the scandal that resulted from the withdrawal of vice-presidential nominee Thomas Eagleton.

Missouri bellwether: The Missouri bellwether is a political phenomenon that notes that the state of Missouri voted for the winner in all but three U.S. Presidential election from 1904 to 2016 (the exceptions are 1956, 2008 and 2012).  While states like Ohio, Iowa, Nevada, and New Mexico have been arguably stronger indicators of political trends in recent years, Missouri was a consistent swing state throughout the 20th century.  Nevada has voted for the winner of every presidential election from United States presidential election, 1912 to the present, excluding United States presidential election, 1976 and United States presidential election, 2016, perhaps making it the new bellwether state.  Prior to the 2008 elections, Lincoln County, Missouri was said to be the only bellwether county in a bellwether state.  Missouri is also considered a bellwether of U.S. views on hot-button social issues such as stem cell research, gay rights, and school vouchers.  Some economists also consider the state a bellwether for economic trends such as consumer confidence and unemployment.

2016 Democratic National Convention: The 2016 Democratic National Convention was a presidential nominating convention, held at the Wells Fargo Center in Philadelphia, Pennsylvania, from July 25 through to July 28, 2016.  The convention gathered delegates of the Democratic Party, the majority of them elected through a preceding series of primaries and caucuses, to nominate a candidate for president and vice president in the 2016 United States presidential election.  Former U.S. Secretary of State, Hillary Clinton, was chosen as the party's nominee for president by a 59.67% majority of delegates present at the convention roll call, defeating primary rival Senator Bernie Sanders, who received 39.16% of votes from delegates, and becoming the first female candidate to be formally nominated for presidential by a major political party in the United States.  Her running mate, Senator Tim Kaine from Virginia, was confirmed by delegates as the party's nominee for vice president by acclamation.

Barack Obama presidential primary campaign, 2008: On February 10, 2007, Barack Obama, then junior United States Senator from Illinois, announced his candidacy for the presidency of the United States in Springfield, Illinois.  On June 3, 2008, he secured enough delegates to become the presumptive nominee of the Democratic Party for the 2008 presidential election.  He was the first African-American in American History to be nominated by a major party.  On November 4, 2008, Obama won the presidential election to become the 44th President of the United States, succeeding George W. Bush.

Democratic Party presidential primaries, 2008: The 2008 Democratic presidential primaries were the selection processes by which voters of the Democratic Party chose its nominee for President of the United States in the 2008 U.S. presidential election.  Senator Barack Obama of Illinois was selected as the nominee, becoming the first African-American to secure the presidential nomination of any major political party in the United States.  However, due to a close race between Obama and Senator Hillary Clinton of New York, the contest remained competitive for longer than expected, and neither candidate received enough pledged delegates from state primaries and caucuses to achieve a majority, without endorsements from unpledged delegates (superdelegates).

Thomas Eagleton: Thomas Francis "Tom" Eagleton (September 4, 1929 – March 4, 2007) was a United States Senator from Missouri, serving from 1968 to 1987.  He is best remembered for briefly being the Democratic vice presidential nominee under George McGovern in 1972.  He suffered from bouts of depression throughout his life, resulting in several hospitalizations, which were kept secret from the public.  When they were revealed it humiliated the McGovern campaign and Eagleton was forced to quit the race.  He later became adjunct professor of public affairs at Washington University in St. Louis.

Physician gag law: In the United States, a physician gag law is a law that prohibits physicians from asking their patients about whether the patient owns a gun.  In some cases, these laws may also restrict the ability of physicians to counsel their patients about gun safety.  The term was first used to describe the "Firearm Owners' Privacy Act," a law that was supported by the National Rifle Association and passed in Florida in 2011, which prohibited doctors from “making written inquiry or asking questions concerning the ownership of a firearm or ammunition by the patient or by a family member of the patient.”  The law passed in Florida was later challenged by the American Academy of Pediatrics, and was blocked in 2012 when judge Marcia G. Cooke, of the United States District Court for the Southern District of Florida, issued an injunction against its implementation.  In 2014, Cooke's decision was reversed by the 11th Circuit Court of Appeals, which ruled to uphold the law.  Since 2011, twelve other states besides Florida have introduced similar laws, and although Florida's is the most restrictive in the country, similar (albeit watered-down) laws have been enacted in Minnesota, Missouri and Montana.

The Delegates: The Delegates were a novelty song group who scored a hit in the United States in 1972.  The "band" was actually Bob DeCarlo, the morning disc jockey at KQV in Pittsburgh, Penn.  Bob was approached by Nick Cenci and Nick Kousaleous, local Pittsburgh record moguls, to make a novelty record.  Bob and the two record men assembled "Convention '72," a "break-in" record which consisted of Bob "imitating" several popular television reporters of the day, including Walter Cronkite ("Walter Klondike"), Chet Huntley ("Sidney Bruntley" as a flamboyantly gay reporter - for some reason), David Brinkley ("David Stinkley"), and Harry Reasoner ("Larry Reasoning") asking questions of current politicians involved in that year's presidential election (such as Thomas Eagleton, Sargent Shriver, Spiro Agnew, Richard Nixon, Edward Kennedy, George McGovern, Martha Mitchell, Jane Fonda and Henry Kissinger) at a joint national "Get Together" convention of Republicans and Democrats, with the responses given as lines from popular songs of the day (in a manner analogous to that made famous by Dickie Goodman).  The tunes sampled in "Convention '72" were (with the artist on the recording):

Libertarian Party presidential primaries, 2016: The 2016 Libertarian Party presidential primaries and caucuses allowed electors to indicate non-binding preferences for the Libertarian Party's presidential candidate.  These differed from the Republican or Democratic presidential primaries and caucuses in that they did not appoint delegates to represent a candidate at the party's convention to select the party's nominee for the United States presidential election.  The party's nominee for the 2016 presidential election was chosen directly by registered delegates at the 2016 Libertarian National Convention, which ran from May 26 to 30, 2016.  The delegates nominated former New Mexico Governor Gary Johnson and former Massachusetts Governor Bill Weld.

United States presidential election, 1996: The United States presidential election of 1996 was the 53rd quadrennial presidential election.  It was held on Tuesday, November 5, 1996.  The Democratic national ticket was led by incumbent President Bill Clinton, and his running mate, incumbent Vice President Al Gore.  The Republican nominee for President was Bob Dole, the former Republican Leader of the United States Senate and long-time Senator from Kansas who was previously the vice-presidential running mate of President Gerald Ford in 1976, following Vice President Nelson Rockefeller's retirement from politics that year.  Dole's running mate for Vice President was Jack Kemp, a former NFL football player and the Housing Secretary under George H. W. Bush.  Businessman Ross Perot ran as candidate for the Reform Party with economist Pat Choate as his running mate; he received less media attention and was excluded from the presidential debates and, while still obtaining substantial results for a third-party candidate, by U.S. standards, did not renew his success of the 1992 election.  Turnout was registered at 49.0%, the lowest for a presidential election since 1924.
