In 1860, Abraham Lincoln ran for President with the campaign slogan "Vote Yourself a Farm", referring to the Republican party's promise to support legislation granting free homesteads to settlers of the Western frontier. Four years later, during the Civil War, he ran for re-election with the slogan "Don't swap horses in the middle of the stream".

Only two future U.S. Presidents signed the Declaration of Independence: Thomas Jefferson and John Adams.

William Howard Taft was the only President of the United States to also serve as Chief Justice of the Supreme Court. In fact, Taft never really wanted to be President. He preferred law to politics and always aspired to serve on the Supreme Court. But his wife -- who wanted to be first lady -- had other ambitions for him. After four uncomfortable years as President, Taft left the White House and became a Professor of Law at Yale. In 1920, Taft finally realized his true dream when President Harding made him Chief Justice of the Supreme Court, a position which he held until just before his death in 1930.

John F. Kennedy won a Pulitzer Prize in 1957 for his book Profiles in Courage, a biography highlighting eight instances in which U.S. Senators risked their careers and stood alone against tremendous political and social pressure for what they felt was right.

In June 1886, Grover Cleveland took 21-year-old Frances Folsom as his wife, making him the first President to be married in the White House. He was also the first President to have a child born there.

During the 1992 Presidential Campaign, Bill Clinton made a surprise appearance on The Arsenio Hall Show -- wearing dark sunglasses, he played "Heartbreak Hotel" on his saxophone. At the time, he was trailing in the polls, and some critics have suggested that this appearance captured the imagination of the American people and turned the race around. In the end, Clinton carried 43 percent of the vote, easily defeating George Bush and Ross Perot and making him the forty-second President of the United States of America.

In the 1964 Presidential campaign, Barry Goldwater used the slogan "In your heart you know he's right". Goldwater had taken a lot of heat from his opponent and the media who labeled him an extremist. This slogan was intended to convince voters that the "extremist" label was unwarranted and that his views were not that different from their own. It was, apparently, unsuccessful as Goldwater carried only 38.5 percent of the vote, losing to Lyndon B. Johnson in a landslide.

Thomas Jefferson had a pet mockingbird named "Dick" which he kept in the White House study. The bird often rode on Jefferson's shoulder and was trained to take small bites of food held between Jefferson's lips at mealtime!

In 1889, at the age of 24, Warren G. Harding had a nervous breakdown and spent several weeks in a sanitarium.

In 2002, Jimmy Carter won the Nobel Peace Prize for "decades of untiring effort to find peaceful solutions to international conflicts, to advance democracy and human rights, and to promote economic and social development". Carter was the third U.S. President to win the Nobel Peace Prize after Woodrow Wilson and Theodore Roosevelt.
