List of United States Senate election results by state

From Wikipedia, the free encyclopedia
Jump to navigation Jump to search

The following table shows regularly-scheduled United States Senate elections by state by year. The table does not include appointments or special elections, though it does include elections that occurred upon a state delegation's admission or readmission to the Senate. The table also includes elections that filled vacancies to unexpired terms that had never been filled due to legislative deadlock or an elected candidate's failure to qualify. The table does not denote post-election party switching. Note that, particularly prior to the ratification of the 17th Amendment in 1913, many regular elections took place in odd years rather than in the preceding even years.

  3. ^ There is no consensus definition for the beginning or ending date of the Sixth Party System.
  4. ^ Two Democrats were elected in 1858, but a Republican replaced one of the Democrats in an 1859 election.
