Liberal-Conservative Party: The Liberal-Conservative Party was the formal name of the Conservative Party of Canada until 1873, and again from 1922 to 1938, although some Conservative candidates continued to run under the label as late as the 1911 election and others ran as simple Conservatives prior to 1873.  In many of Canada's early elections, there were both "Liberal-Conservative" and "Conservative" candidates; however, these were simply different labels used by candidates of the same party.  Both were part of Sir John A. Macdonald's government and official Conservative and Liberal-Conservative candidates would not, generally, run against each other.  It was also common for a candidate to run on one label in one election and the other in a subsequent election.

Maryland gubernatorial election, 1966: The Maryland gubernatorial election of 1966 was held on November 8, 1966.  Incumbent Democratic Governor J. Millard Tawes was unable to seek a third term in office.  In the election to succeed him, George P. Mahoney, a controversial segregationist, emerged from the Democratic primary due to splintered support for the two major candidates.  Baltimore County Executive Spiro Agnew, who would later go on to be selected by Richard M. Nixon as his running mate in 1968, was nominated by the Republican Party as their gubernatorial candidate.  Mahoney and Agnew squared off, along with independent candidate Hyman A. Pressman.  Ultimately, Agnew was victorious over Mahoney, with Pressman a distant third.  This year would be the last time that the state of Maryland elected a Republican governor until 2002.

Democratic Party presidential primaries, 1924: The 1924 Democratic presidential primaries were part of the selection process by which voters of the Democratic Party chose its nominee for President of the United States in the 1924 U.S. presidential election.  The concept of a primary election, where any registered party member would vote for a candidate, was relatively new in the American political landscape.  In only 12 states were actual primaries held, and even in those the results were not universally binding for the delegates to the Democratic National Convention, where the presidential candidate would be formally chosen.  In most of the country, the selection of delegates was confined to state-level conventions and caucuses, under the heavy hand of local political machines. Though William Gibbs McAdoo won a vast majority of states, and much more than half of the popular vote, in those twelve states that held primary elections, it meant little to his performance nationwide.  Many of the delegations from states that did "not" hold primary elections favored his main rivals, Oscar Underwood of Alabama and Al Smith of New York, neither of which won any primary elections.  As well, the primaries that McAdoo did not win were won by "local sons" who stood no chance of winning the nomination, or in some cases were not even formal candidates.  Once at the convention, the party was deadlocked for 102 straight ballots, before dark horse candidate John W. Davis, (who was not a formal candidate when he arrived at the convention) was chosen on the 103rd ballot.  Davis went on to lose the election to Republican candidate Calvin Coolidge.

Dixiecrat: The States' Rights Democratic Party (usually called the Dixiecrats) was a short-lived segregationist political party in the United States.  It originated in 1948 as a breakaway faction of the Democratic Party determined to protect states' rights to legislate racial segregation from what its members regarded as an oppressive federal government.  Supporters assumed control of the state Democratic parties in part or in full in several Southern states.  The Party opposed racial integration and wanted to retain Jim Crow laws and white supremacy in the face of possible federal intervention.  Its members were referred to as "Dixiecrats", a portmanteau of "Dixie", referring to the Southern United States, and "Democrat".
