Context paragraphs:
United States presidential election: The election of President and Vice President of the United States is an indirect election in which citizens of the United States who are registered to vote in one of the 50 U.S. states or Washington, D.C. cast ballots for members of the U.S. Electoral College, known as electors.  These electors then in turn cast direct votes, known as electoral votes, for President and Vice President.  The candidate who receives an absolute majority of electoral votes for President or Vice President (currently, at least 270 out of a total of 538) is then elected to that office.  If no candidate receives an absolute majority for President, the House of Representatives chooses the President; if no one receives a majority for Vice President, then the Senate chooses the Vice President.

Colorado Amendment 36: In the November 2004 United States election, one of the issues up for a vote in the state of Colorado was known as Amendment 36.  It was a ballot initiative for an amendment to the state constitution.  It would have changed the way in which the state apportioned its electoral votes.  Rather than assigning all 9 of the state's electors to the candidate with a plurality of popular votes, under the amendment, Colorado would have assigned presidential electors proportionally to the statewide vote count, which would be a unique system (Nebraska and Maine assign electoral votes based on vote totals within each congressional district).  The amendment did not pass.

Pat McCarran: Patrick Anthony McCarran (August 8, 1876 – September 28, 1954) was a Democratic United States Senator from Nevada from 1933 until 1954.  McCarran was born in Reno, Nevada, attended the Nevada State University, and was a farmer and rancher.  In 1902 he won election to the Nevada Assembly, but in 1904 he was an unsuccessful candidate for the Nevada State Senate.  He completed private law studies and was admitted to the bar in 1905; in 1906 he won election as Nye County's district attorney.  He served a two-year term, after which he relocated to Reno.

United States presidential election, 1964: The United States presidential election of 1964 was the 45th quadrennial presidential election.  It was held on Tuesday, November 3, 1964.  Democratic candidate and incumbent President Lyndon B. Johnson had come to office less than a year earlier following the assassination of his predecessor John F. Kennedy.  Johnson, who had successfully associated himself with Kennedy’s popularity, won 61.1% of the popular vote, the highest win by a candidate since James Monroe’s re-election in 1820.  It was the most lopsided US presidential election in terms of popular votes, and the tenth-most lopsided presidential election in the history of the United States in terms of electoral votes.  No candidate for president since has equalled or surpassed Johnson’s percentage of the popular vote, and since 1820, only Abraham Lincoln in 1864, Franklin D. Roosevelt in 1936, Richard Nixon in 1972 and Ronald Reagan in 1980 and 1984 have won by a greater electoral vote margin.

Patrick, Nevada: Patrick is an unincorporated community in Storey County which was the site of a historic ranch.  The founder of the ranch, Patrick McCarran, arrived in Nevada in 1858 as a member of the United States Army under General Winfield Scott Hancock.  In 1862 McCarran claimed 2600 acre of land that would become McCarran Ranch and the unincorporated community of Patrick.  Patrick's son, Pat McCarran, became Nevada's first native born U.S. Senator and a staunch anti communist.  Patrick Nevada is also the owner of four of the cattle in the ranch.

United States presidential election, 1876: The United States presidential election of 1876 was the 23rd quadrennial presidential election, held on Tuesday, November 7, 1876.  It was one of the most contentious and controversial presidential elections in American history.  The results of the election remain among the most disputed ever, although it is not disputed that Samuel J. Tilden of New York outpolled Ohio's Rutherford B. Hayes in the popular vote.  After a first count of votes, Tilden won 184 electoral votes to Hayes's 165, with 20 votes unresolved.  These 20 electoral votes were in dispute in four states.  In the case of Florida, Louisiana, and South Carolina, each party reported its candidate had won the state, while in Oregon one elector was replaced after being declared illegal for being an "elected or appointed official".  The question of who should have been awarded these electoral votes is the source of the continued controversy concerning the results of this election.

United States presidential election in Utah, 1908: The 1908 United States presidential election in Utah was held on November 3, 1908 throughout all forty-six contemporary states.  Utah voters chose three representatives, or electors to the Electoral College, who voted for President and Vice-President.  This was the last election when Utah had the minimum three electoral votes as it would gain a second congressional district after the 1910 Census.

History of Nevada: Nevada became the 36th state on October 31, 1864, after telegraphing the Constitution of Nevada to the Congress days before the November 8 presidential election (the largest and costliest transmission ever by telegraph).  Statehood was rushed to help ensure three electoral votes for Abraham Lincoln's reelection and add to the Republican congressional majorities.

Bibliography of Abraham Lincoln: This bibliography of Abraham Lincoln is a comprehensive list of written and published works about or by Abraham Lincoln, 16th President of the United States.  In terms of primary sources containing Lincoln's letters and writings, scholars rely on "The Collected Works of Abraham Lincoln", edited by Roy Basler, and others.  It only includes writings by Lincoln, and omits incoming correspondence.  In the six decades since Basler completed his work, some new documents written by Lincoln have been discovered.  Currently, a project is underway at the Papers of Abraham Lincoln to provide "a freely accessible comprehensive electronic edition of documents written by and to Abraham Lincoln".  The Papers of Abraham Lincoln completed Series I of their project "The Law Practice of Abraham Lincoln" in 2000.  They electronically launched "The Law Practice of Abraham Lincoln, Second Edition" in 2009, and published a selective print edition of this series.  At present they are engaged in locating, digitizing, and transcribing documents for Series II (non-legal, pre-presidential materials) and Series III (presidential materials).
