1806 and 1807 United States Senate elections


The United States Senate elections of 1806 and 1807 were elections that had the Democratic-Republican Party increase its overwhelming control of the Senate by one additional Senator. The Federalists went into the elections with such a small share of Senate seats that even if they had won every election, they would still have remained a minority caucus. As it was, however, they lost one of the two seats they were defending and picked up no gains from their opponents.
As these elections were prior to ratification of the seventeenth amendment, Senators were chosen by state legislatures.
