2016 United States Senate election in Maryland

Mikulski first ran for the U.S. Senate in 1974, losing to Republican incumbent Charles Mathias. Mikulski then served in the U.S. House of Representatives from 1977 to 1987 and was elected to the U.S. Senate in 1986, succeeding the retiring Mathias. She was re-elected by large margins in 1992, 1998, 2004 and 2010. Shortly after being sworn in for her fifth term in 2011, she succeeded Margaret Chase Smith as the longest-serving female senator in U.S. history,Marbella, Jean [https://www.baltimoresun.com/2011/01/05/mikulskis-milestone-the-senates-longest-serving-woman/ "Mikulski's milestone: the Senate's longest-serving woman"] The Baltimore Sun January 5, 2011 and on March 17, 2012, she became the longest-serving female member of Congress in U.S. history, surpassing Congresswoman Edith Nourse Rogers of Massachusetts, who served from 1925 to 1960.[http://www.cnn.com/2012/03/16/politics/mikulski-history/index.html?hpt=hp_t3 CNN.com: Mikulski makes history while creating 'zone of civility' for Senate women] On March 2, 2015, Mikulski announced that she would not run for re-election to a sixth term in office.

In August 2013, Abby Livingston of Roll Call had predicted that a potential retirement by Mikulski would create "chaos" and "blow open Maryland's political bottleneck" because "the state's teeming political Democratic Party talent is backed up in lower offices."{{cite web | url=http://www.rollcall.com/news/chaos_comes_in_marylands_next_open_senate_race_farm_team-227010-1.html | title=Chaos Comes in Maryland's Next Open Senate Race {{!}} Farm Team | date=August 12, 2013 | access-date=November 21, 2014 | author=Abby Livingston | work=Roll Call}} Among the ten Democrats who ran in the primary, only two had previously been elected to an office.
