1788 and 1789 elections

[edit]

These were the first Senate elections, which coincided with the election of President George Washington. As of this election, formal organized political parties had yet to form in the United States, but two political factions were present: The coalition of senators who supported George Washington's administration were known as "Pro-Administration," and the senators against him as "Anti-Administration." Members are informally grouped into factions of similar interest, based on an analysis of their voting record.[1]

These elections expanded the Democratic-Republicans' overwhelming control of the Senate. The Federalists went into the elections with such a small share of seats (9 out of 34, or 26%) that even had they won every election, they would have still remained a minority caucus.

Coinciding with President James Madison's re-election, the Democratic-Republican Party lost two seats but still retained an overwhelming majority in the Senate. As in recent elections, the minority Federalists had gone into the elections with such a small share of Senate seats that if they had won every one of the elections, they would still not have controlled a majority.

[edit]

The Democratic-Republicans lost a seat but still retained an overwhelming majority in the Senate. Unlike in recent elections, the minority Federalists had gone into the elections with a change of regaining their long-lost majority had they swept almost all the seats. However, only one seat switched parties. Two seats held by Democratic-Republicans were left unfilled until long after the next Congress began.

1910 and 1911 elections

[edit]

Although the 17th Amendment was not passed until 1913, some states elected their Senators directly before its passage. Oregon pioneered direct election and experimented with different measures over several years until it succeeded in 1907. Soon after, Nebraska followed suit and laid the foundation for other states to adopt measures reflecting the people's will. By 1912, as many as 29 states elected senators either as nominees of their party's primary or in conjunction with a general election.
