1812–13 United States Senate elections
The 1812–13 United States Senate elections were held on various dates in various states, coinciding with President James Madison's re-election. As these U.S. Senate elections were prior to the ratification of the Seventeenth Amendment in 1913, senators were chosen by state legislatures. Senators were elected over a wide range of time throughout 1812 and 1813, and a seat may have been filled months late or remained vacant due to legislative deadlock. In these elections, terms were up for the senators in Class 3. The Democratic-Republican Party lost two seats but still retained an overwhelming Senate majority. As in recent elections, the minority Federalists had gone into the elections with such a small share of Senate seats (6 out of 36, or 16.7%) that if they had won every one of the elections, they would still not have controlled a majority.
