1788 and 1789 elections[]
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]

1910 and 1911 elections[]
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.
