History

The Federalists of the 1790s made "democrat" a word of ridicule, comparing the followers of Thomas Jefferson to the murderous fanatics of the French Revolution. In a private letter in September 1798, George Washington wrote, "You could as soon as scrub the blackamore white, as to change the principles of a profest [professed] Democrat; and that he will leave nothing unattempted to overturn the Government of this Country." Jefferson's Anti-Federalist supporters adopted the name and became known as Democratic-Republicans.

19th century

In American history, many parties were named by their opponents: (Federalists, Loco-Focos, Know Nothings, Populists, Dixiecrats), including the Democrats themselves, as the Federalists in the 1790s used Democratic Party as a term of ridicule. Addressing a gathering of Michigan Republicans in 1889, New Hampshire Republican Congressman Jacob H. Gallinger said: The great Democrat party, laying down the sceptre of power in 1860, after ruling this country under free trade for a quarter of a century, left our treasury bankrupt, and gave as a legacy to the Republican party, a gigantic rebellion and a treasury without a single dollar of money in it.

According to the Oxford English Dictionary the term was used by the press in London, England, as a synonym for the more common Democratic Party in 1890: Whether a little farmer from South Carolina named Tillman is going to rule the Democrat Party in America—yet it is this, and not output, on which the proximate value of silver depends.

Early 20th century

The 1919 New Teachers' and Pupils' Cyclopaedia entry for Woodrow Wilson states that "In 1912, Wilson was the Democrat Party nominee for President ..." On July 14, 1922, a newspaper in Keytesville, Missouri, posted an advertisement for its primary elections with the Democratic candidates identified as "Representing: Democrat Party".

Late 20th century

The noun-as-adjective has been used by Republican leaders since the 1940s, and in most GOP national platforms since 1948. By the early 1950s, the term was in widespread use among Republicans of all factions. When Senator Thruston Ballard Morton became chairman of the Republican National Committee in 1959, he indicated that he had always said Democratic Party and would continue to do so, which contrasted with his predecessor, Meade Alcorn, and with National Republican Senatorial Committee chairman Barry Goldwater, both of whom used Democrat Party. According to Congressional Quarterly, at the 1968 Republican National Convention "the GOP did revert to the epithet of 'Democrat' party. The phrase had been used in 1952 and 1956 but not in 1960 and 1964".

According to William Safire, Minnesota Governor Harold Stassen, campaign manager to Republican Wendell Willkie during the 1940 presidential campaign, explained that because the Democratic Party was at that time partly controlled by undemocratic city bosses, "by Hague in New Jersey, Pendergast in Missouri and Kelly-Nash in Chicago, [it] should not be called a 'Democratic Party.' It should be called the 'Democrat Party.' "
