Context: Joan Lacey Mazauskas (January 25, 1933 - April 23, 2003) was an American author and Republican Party politician.  She was the author of "Mayday!  Mayday!  Eastern Airlines In A Tailspin!"  (1990).  In 1977, Mazauskas sought the Republican nomination for State Senator in the 28th legislative district of New Jersey, where Democratic incumbent Martin L. Greenberg was seeking re-election to a second term.  The GOP primary included three candidates, each aligned with a different candidate for the Republican nomination for Governor: Joan Lacey Mazauskas ran with State Sen. Raymond Bateman, Rev. James A. Pindar ran on a line with Assembly Minority Leader Thomas Kean; and Rocco Clarizio was allied with former Senate Minority Leader C. Robert Sarcone.  Pindar defeated Mazauskas by just 207 votes, 1,482 (42.04%) to 1,275 (36.17%), while Clarizio ran a distant third with 768 votes (21.79%).  Her husband, George Mazauskas, served as a Town Councilman in Irvington, New Jersey. Joseph Patrick Monaghan (March 26, 1906 – July 4, 1985) of Butte, Montana was a U.S. Representative from Montana from 1933 to 1937.  He was a Democrat.  In 1936 he decided not to run for reelection and instead challenged Democratic incumbent United States senator James E. Murray in the Democratic primary.  When Murray won, Monaghan ran in the general election as an independent.  Murray soundly defeated Monaghan and Republican T.O. Larsen.  Murray received 55% of the vote, Larsen 27% of the vote and Monaghan 18%.  At the age of 30, Monaghan's political career came to an end.  He returned to his law practice, and returned to politics only briefly in 1964 when he ran for the Democratic nomination unsuccessfully for the United States Senate in Montana, against Senate Majority leader Mike Mansfield.

She is the first woman to be elected as a senator for Minnesota and is one of twenty-one women serving in the current United States Senate. The 2012 United States Senate election in Minnesota took place on November 6, 2012, concurrently with the U.S. presidential election as well as other elections to the United States Senate and House of Representatives as well as various state and local elections.

He ran for the U.S. House of Representatives in 1964 and for the New Jersey State Senate in 1977, but lost both times in the Republican primary.  In 1964, Clarizio became a candidate for Congress in New Jersey’s 10th district, seeking to challenge Democratic incumbent Peter W. Rodino.  In a historic primary where he was the only white candidate, Clarizio finished third behind two Black Republicans, William L. Stubbs and Dr. Harold R. Scott.  Stubbs, who became the first Black to win a major party nomination for Congressman from New Jersey, won 5,148 (63%) to 2,217 (26%) for Scott, with Clarizio finishing third with 892 votes (11%).  In 1977, Clarizo sought the Republican nomination for State Senator in the 28th legislative district, where Democratic incumbent Martin L. Greenberg was seeking re-election to a second term.  The GOP primary included three candidates, each aligned with a different candidate for the Republican nomination for Governor: Rev. James A. Pindar ran on a line with Assembly Minority Leader Thomas Kean; Joan Lacey Mazauskas ran with State Sen. Raymond Bateman, and Clarizio was allied with former Senate Minority Leader C. Robert Sarcone.  Pindar defeated Mazauskas by just 207 votes, 1,482 (42.04%) to 1,275 (36.17%), while Clarizio ran a distant third with 768 votes (21.79%).
