"The Dream Shall Never Die" was a speech delivered by U.S. Senator Ted Kennedy at the Democratic National Convention on August 12, 1980.
 In the address, Kennedy defended post-World War II liberalism, advocated for a national healthcare insurance model, criticized former actor and Republican presidential nominee Ronald Reagan, and implicitly rebuked incumbent President Jimmy Carter (to whom he had conceded the Democratic nomination only the night before) for his more moderate political stances.
 It has been remembered by some as Kennedy's best speech, and one of the most influential orations of the era.
The 1980 Democratic presidential primaries were the selection process by which voters of the Democratic Party chose its nominee for President of the United States in the 1980 U.S. presidential election.
 Incumbent President Jimmy Carter was again selected as the nominee through a series of primary elections and caucuses culminating in the 1980 Democratic National Convention held from August 11 to August 14, 1980, in New York City.
 It is notable for being the last time that an incumbent president lost a state's presidential primary.
The presidency of Ronald Reagan began on January 20, 1981, when Ronald Reagan was inaugurated as President of the United States, and ended on January 20, 1989.
 Reagan, a Republican, took office as the 40th United States president following a landslide win over Democratic incumbent President Jimmy Carter in the 1980 presidential election.
 Reagan was succeeded by his vice president, George H. W. Bush, who won the 1988 presidential election with Reagan's support.
The 1916 Republican National Convention was held in Chicago from June 7 to June 10.
 A major goal of the party's bosses at the convention was to heal the bitter split within the party that had occurred in the 1912 presidential campaign.
 In that year, Theodore Roosevelt bolted the GOP and formed his own political party, the Progressive Party, which contained most of the GOP's liberals.
 William Howard Taft, the incumbent president, won the nomination of the regular Republican Party.
 This split in the GOP ranks divided the Republican vote and led to the election of Democrat Woodrow Wilson.
 Although several candidates were openly competing for the 1916 nomination—most prominently conservative Senator Elihu Root of New York, Senator John W. Weeks of Massachusetts, and liberal Senator Albert Cummins of Iowa—the party's bosses wanted a moderate who would be acceptable to all factions of the party.
 They turned to Supreme Court Justice Charles Evans Hughes, who had served on the court since 1910 and thus had the advantage of not having publicly spoken about political issues in six years.
 Although he had not sought the nomination, Hughes made it known that he would not turn it down; he won the nomination on the third ballot.
 Former Vice-President Charles W. Fairbanks was nominated as his running mate.
 Hughes was the only Supreme Court Justice to be nominated for president by a major political party.
 Fairbanks (as of 2016) was the last former vice president, to be nominated for vice president.
The 1960 presidential campaign of John F. Kennedy, a United States Senator from Massachusetts, began on January 2, 1960, when Kennedy formally announced his candidacy for 35th President of the United States, replacing incumbent President of the United States Dwight D. Eisenhower.
 Kennedy was nominated by the Democratic Party at the Democratic National Convention of 1960, taking place between July 11 and July 15, 1960.
 On July 15, 1960, Kennedy named Senator Lyndon B. Johnson of Texas as his official running mate.
 Kennedy and Johnson won the election on November 8, 1960, defeating incumbent Vice President and Republican nominee Richard Nixon, who would later go on to be the 37th President of the United States.
 Kennedy and Johnson were sworn in as 35th President and 37th Vice President of the United States on January 20, 1961 respectively.
 Kennedy would serve as President of the United States until his death in November 1963.
"Life Begins at 40" is a song by John Lennon.
 It was written in 1980, the year that both Lennon and Ringo Starr turned 40 years of age.
 Lennon recorded a demo of the song at his home, but it was not recorded at any of the sessions for his comeback album, "Double Fantasy."
 Instead, he intended to give the song to Starr to record on his own forthcoming album, "Can't Fight Lightning."
 The song's amiable country feel was well suited to Starr's singing style.
 After Lennon's murder in December 1980, those plans were shelved.
 However, Lennon's demo was eventually issued in 1998 on the "John Lennon Anthology" box set.

The United States presidential election of 1912 was the 32nd quadrennial presidential election, held on Tuesday, November 5, 1912.
 The election was a rare four-way contest.
 Incumbent President William Howard Taft was renominated by the Republican Party with the support of its conservative wing.
 After former President Theodore Roosevelt failed to receive the Republican nomination, he called his own convention and created the Progressive Party (nicknamed the “Bull Moose Party”).
 It nominated Roosevelt and ran candidates for other offices in major states.
 Democrat Woodrow Wilson was finally nominated on the 46th ballot of a contentious convention, thanks to the support of William Jennings Bryan, the three-time Democratic presidential candidate who still had a large and loyal following in 1912.
 Meanwhile, the Socialist Party of America renominated its perennial standard-bearer, Eugene V. Debs.
 It is the last election in which a former, or incumbent, President (Roosevelt) ran for the office without being nominated as either a Democrat or Republican.
 It is also the last election in which an incumbent president running for re-election (Taft) failed to finish either first or second in the popular vote count.
