List of United States Senate election results by state explained

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.
