The Hubert Humphrey presidential campaign of 1968 began when Vice President of the United States Hubert Humphrey of Minnesota decided to seek the Democratic Party nomination for President of the United States following the announcement by President Lyndon B. Johnson that he would not seek the party's nomination.  Johnson had been stalled by the anti-Vietnam War candidacy of Senator Eugene McCarthy of Minnesota, who along with Senator Robert F. Kennedy of New York, became the main opponents for Humphrey.  The contest between the men featured a battle for control of the Democratic Party, and cast Humphrey's "old politics", against the "new politics" of McCarthy and Kennedy.  The main cause of the division was the Vietnam War, which intensified during Humphrey's tenure as Vice President and grew increasingly unpopular.

Duncan held the office longer than any other county executive in the county's history.  In 2006, Duncan was a candidate for the Democratic nomination in the Maryland gubernatorial election.  He abruptly dropped out of the race on June 22, 2006, citing clinical depression, handing the nomination to Baltimore Mayor Martin O'Malley.  Following his exit from the gubernatorial race, he was appointed Vice President of Administrative Affairs of the University of Maryland, College Park, where he worked for 17 months.

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.
