The 1886–87 United States Senate elections were held on various dates in various states. 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 1886 and 1887, and a seat may have been filled months late or remained vacant due to legislative deadlock.[1] In these elections, terms were up for the senators in Class 1.
The Republican Party lost two seats. At the beginning of the 50th Congress, therefore, Republicans had the slimmest possible majority due to a vacant Democratic seat: 38 out of 75 seats. Once that vacancy was filled, Republicans maintained control as the single Readjuster senator caucused with them.

The caucus of Republican State legislators met on January 17, President pro tempore of the State Senate Edmund L. Pitts presided. 20 State senators and 71 assemblymen attended. Ex-Speaker of the Assembly George Z. Erwin (a Morton man) moved that a majority of all Republican legislators should be necessary to nominate, not only a majority of those present, meaning that 48 votes were required instead of 46, which was carried by a vote of 52 to 39. The incumbent U.S. senator Warner Miller (Half-Breed faction) failed to be nominated by only four votes. Levi P. Morton (Stalwart faction) was rejected by the caucus, like in 1885. A small faction voted for Congressman Frank Hiscock. After the second ballot, Erwin moved to adjourn, which was carried by 48 to 43. The caucus met again on the next day, no choice was made in another two ballots. The caucus met again on January 19 after the joint ballot of the State Legislature, and after twelve more ballots, Erwin withdrew Morton's name and urged the Morton men to vote for Hiscock. On the next ballot Hiscock received one vote more than Miller (47 to 46), but was one short of the previously established majority of 48. On the 18th and last ballot, Hiscock received 50 votes and was nominated. On the next day, Hiscock was elected on the second joint ballot of the State Legislature. Thus, by blocking Miller's re-election, the Republican boss Thomas C. Platt took his revenge for his defeat at the special election in 1881.
