Senate Seniority List – Democrats: 113th Congress

Updated February, 2014

Source: http://www.senate.gov/artandhistory/history/resources/pdf/chronlist.pdf

 

Senate rank is first determined by the length of consecutive service in the Senate. For senators who entered the Senate on the same day, several tie-breaking procedures determine seniority. In order of precedence, these factors are: previous Senate service, service as the vice president, previous House service; service in the Cabinet, service as a state governor. If a tie still exists, senators are ranked according to the population of their state at the time of swearing in.
