She was the first female African-American Senator, the first African-American U.S. Senator for the Democratic Party, the first woman to defeat an incumbent U.S. Senator in an election, and the first female Senator from Illinois.

From 1999 until 2001, she was the United States Ambassador to New Zealand.  She was a candidate for the Democratic nomination during the 2004 U.S. presidential election.

It was the largest political party of that time, uniting the major parties of Senator Edgardo Angara (LDP-Aurora)'s Laban ng Demokratikong Pilipino (Struggle of Democratic Filipinos), tycoon Eduardo Cojuangco Jr.'s Nationalist People's Coalition, Vice President Joseph Estrada's Partido ng Masang Pilipino (Party of the Filipino Masses) and along with minor and regional parties.

Louisiana gubernatorial election, 1892: The Louisiana gubernatorial election of 1892 was held on April 19, 1892.  Like most Southern states between Reconstruction and the civil rights era, Louisiana's Republican Party was virtually nonexistent in terms of electoral support.  In addition, the Republican Party had split into two factions, each supporting a different candidate.  As Louisiana had not yet adopted party primaries, this meant that the Democratic Party convention nomination vote was supposed to be the real contest over who would be governor.  At the convention, pro-lottery former Governor Samuel D. McEnery was nominated.  As a result of the nomination of a pro-lottery candidate, a group of anti-lottery Democrats nominated their own candidate, State Senator Murphy J. Foster.  In addition to the four candidates already mentioned, the increasingly popular Populists nominated R. H. Tannehill and their candidate.  Despite all of this, Senator Foster was elected with 45% of the vote with a comfortable 19% margin between him and McEnery, who placed second.  This election marked the last time until 1979 that the official Democratic Party nominee was defeated.

Jack Hunter (radio host): Jack William Hunter, Jr. (born June 1, 1974) is an American radio host, political commentator and Politics Editor for Rare.us, a Washington, D.C.-based news website.  He began his career in the late 1990s on alternative rock station WAVF 96.1 FM using the moniker "Southern Avenger", an anonymous pro wrestler/superhero-style character.  In 2007, Hunter began appearing every Tuesday and Friday morning on WTMA News-Talk 1250 AM, and contributed to a weekly column to the "Charleston City Paper".

He is perhaps best known for his decades-old, racially-charged writings whose reemergence caused a major media controversy for his boss, Senator Paul.

1916 Republican National Convention: 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.

He had been member of the Friesland provincial legislature for the Frisian National Party.  He remained senator and leader of the party until 2011, when his role was taken over by Kees de Lange.  In 2015, Henk ten Hoeve became again senator.  The main parties involved are the Frisian National Party, the Party for the North, the Party New Limburg and the Brabant Party.

Smith ran for reelection to a second term, defeating Republican State Senator Don Lorenzo Hubbell in the general election by a wide margin.

John Shannon (Australian politician): John Wallace Shannon (28 April 1862 – 30 January 1926) was an Australian politician.  Born in Angaston, South Australia, where he was educated, he became a farmer on the Yorke Peninsula and an auctioneer.  He served on Maitland Council, of which he was mayor.  In 1896, he was elected to the South Australian House of Assembly for Yorke Peninsula, transferring to Wallaroo in 1902.  He left the Assembly in 1905.  In 1912, he was appointed to the Australian Senate as a Liberal Senator for South Australia, filling the casual vacancy caused by the death of Labor Senator William Russell.  This was the first time a state government had successfully replaced a Senator with a Senator of a different party, after Labor's failed attempt in 1907 to appoint James O'Loghlin to succeed Joseph Vardon.  Defeated in 1913, he was elected in 1914 with over 95% of the vote due to the death of Labor Senator Gregor McGregor, which left the Labor Party with only five nominees.  They directed the sixth vote to Shannon, resulting in an easy return to the Senate.  He joined the Nationalist Party when it formed in 1917, and from 1917 to 1920 served as Chairman of Committees.  Shannon did not stand at the 1919 federal election, and his term ended on 30 June 1920.  He died in 1926.
