The 1912–13 United States Senate elections were held on various dates in various states. They were the last U.S. Senate elections before the ratification of the Seventeenth Amendment in 1913, establishing direct elections for all Senate seats. Senators had been primarily chosen by state legislatures. Senators were elected over a wide range of time throughout 1912 and 1913, and a seat may have been filled months late or remained vacant due to legislative deadlock.^[1] Some states elected their senators directly even before passage of Seventeenth Amendment. 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.

In these elections, terms were up for the senators in Class 2. The Democrats gained control of the Senate for the first time in 20 years. Of the 32 seats up for election, 17 were won by Democrats, thereby gaining 4 seats from the Republicans. Two seats were unfilled by state legislators who failed to elect a new senator on time.

These elections coincided with Democrat Woodrow Wilson's victory in the presidential election amid a divide in the Republican Party. In the Senate, Joseph M. Dixon and Miles Poindexter defected from the Republican Party and joined Theodore Roosevelt's new Progressive Party. Dixon, however, lost his seat during this election.

Arizona became a new state February 14, 1912, with senators in classes 1 (ending 1917) and 3 (ending 1915). For the initial senators there was a popular vote held December 12, 1911 — before statehood — and the newly formed state legislature effectively ratified the popular votes March 26, 1912: Democrat Henry F. Ashurst (class 1) and Democrat Marcus A. Smith (class 3).

Henry F. Ashurst was elected to the Territorial House of Representatives in 1897. He was re-elected in 1899, and became the territory's youngest speaker. In 1902, he was elected to the Territorial Senate. In 1911, Ashurst presided over Arizona's constitutional convention.^[27] During the convention, he positioned himself for a U.S. Senate seat by avoiding the political fighting over various clauses in the constitution which damaged his rivals.^[28]

In 1913, however, Democrats were in control of the legislature, Saulsbury was the preference of most Democrats, and he obtained the required majority January 29, 1913, after several days of balloting. This election was the first time since 1883 that a Democrat won a full term for this Senate seat in Delaware.

On June 15, 1913, Bacon was elected by the general populace without opposition, becoming the first senator elected under the Seventeenth Amendment to the United States Constitution.

Bacon died in early 1914, however, leading to another interim appointment and eventual special election.

In the November 1912 state elections, the Republicans lost control of the state due to the Republican / Progressive split. But while the Democrats held a plurality of the Illinois General Assembly, they did not have a majority. The General Assembly took up the matter of electing the senators on February 1. The General Assembly therefore failed to elect until after the new congress began.

On March 26, in a compromise arranged by governor Dunne, the General Assembly elected Democrat J. Hamilton Lewis to fill the full-term seat and Republican Lawrence Y. Sherman to fill the two remaining years of a vacancy that had just recently opened.

On April 12, 1912, five-term Republican incumbent Shelby Moore Cullom lost renomination to Lieutenant Governor of Illinois Lawrence Y. Sherman in the Republican "advisory" primary, where the voters expressed their preference for senator but the decision was not binding on the General Assembly, which made the actual choice. Cullom had suffered politically over his support for the other Illinois senator, William Lorimer, who was embroiled in a scandal over alleged bribery in his 1909 election to the Senate.

After his defeat, Cullom withdrew his name from consideration by the General Assembly.

The Illinois General Assembly eventually elected the Democratic nominee, Congressman J. Hamilton Lewis March 26, 1913, who had also won the Democratic advisory primary, as the sole candidate on the ballot.

Thompson would only serve one term, losing re-election in 1918. As of 2023, this is the last time the Democrats won the Class 2 Senate seat in Kansas. This represents the longest current winning streak of either party for a single Senate seat.

Curtis' political career, meanwhile, would rebound, as he was elected to Kansas' other US Senate seat, first by defeating Kansas' senior senator Joseph L. Bristow in the Republican primary, and then winning re-election nonconsecutively to the U.S Senate by a very narrow margin over two opponents, becoming the first Kansan to be popularly elected to the U.S Senate in a historic first. Curtis would serve in the Senate for three terms before resigning to become U.S. Vice President in March 1929, the first Native American to serve in that office.

Lee presented his credentials to serve as senator on December 5, 1913, but he did not qualify until January 28, 1914, because Jackson claimed that "since [Jackson] had been appointed under the original constitutional provision, [Jackson] was entitled to hold his seat until the regularly scheduled adjournment date of the Maryland state assembly."^[25] The Senate considered Jackson's challenge but eventually rejected it and seated Lee.

Lee would only serve this one term, as he lost renomination in 1916.

U.S. senator before election LeRoy Percy Democratic Elected U.S. senator James K. Vardaman Democratic

One-term Democrat LeRoy Percy lost renomination in mid-1911 to white supremacist James K. Vardaman, who was then elected January 16, 1912, to the seat, unopposed.^[2]

Percy had won in 1910 (to finish a vacant term) despite Vardaman's support of a plurality of legislators (all white). The fractured remainder sought to thwart his extreme racial policies. A majority united behind Percy to block Vardaman's election. Percy had advocated education for blacks and worked to improve race relations by appealing to the planters' sense of noblesse oblige. Disenfranchisement of blacks made the Democratic primary the deciding competitive race for state and local offices in Mississippi.

In this rematch, Vardaman's campaign was managed by Lieutenant Governor of Mississippi (and future senator) Theodore Bilbo, who emphasized class tensions and racial segregation, attacking Percy as a representative of the aristocracy of the state and for taking a progressive stance on race relations.

Vardaman, however, would only serve one term, losing renomination in 1918, primarily due to his vote against entry into World War I.

Despite the Democratic majority, the Nebraska legislature elected Republican Norris unanimously, upholding the popular vote.^[47]

"The Democratic Legislature will be called upon to elect a Republican for United States Senator. Ninety-five per cent. [sic] of the candidates for the Legislature, in accordance with the Oregon plan, signed "Statement No. 1," which provides that, in the event of election, they will vote for the candidate for United States Senator who obtains the preference vote of the people. Although Congressman Norris, a Progressive Republican, has won the preference vote, returns indicate that a Democratic legislature has been elected."^[48]

Norris would serve for thirty years, winning two more elections as a Republican and one as an Independent but losing re-election in 1942.

Republican senator George S. Nixon died June 5, 1912. Republican former-judge William A. Massey was appointed July 1, 1912, to continue the term that would end in 1917, pending a special election.

Two-term Republican Henry E. Burnham decided to retire. The New Hampshire legislature failed to elect a new senator after 42 votes, so the March 4, 1913, term begin with the seat vacant.

Finally, on March 26, 1913, on the 43rd vote, Democrat Henry F. Hollis was elected with the required majority, albeit slight. Hollis was a former candidate for U.S. House of Representatives (in 1900), and twice for Governor of New Hampshire (in 1902 and 1904).

New Mexico became a new state January 6, 1912, with senators in classes 1 (ending 1917) and 2 (ending 1913). On March 27, 1912, the state elected its initial senators on the eighth ballot:^[52] Republican Thomas B. Catron, an early advocate for New Mexico statehood who had marshaled the territorial Republican Party to lobby Republicans at the national level for New Mexico's admission to the Union,^[53][54][55] and Republican Albert B. Fall, a powerful attorney, former territorial attorney general, future Secretary of the Interior, and instigator of the Teapot Dome scandal)

Catron made a personal alliance with Fall, ensuring that each of them would be elected. This alliance antagonized New Mexicans of Spanish heritage, who had hoped that one of their own would become a Senator.^[56]

Y Albert B. Fall (Republican) 39 votes (Class 2) Y Thomas B. Catron (Republican) 38 votes (Class 1) Felix Martinez (Democratic) 25 votes Andrieus A. Jones (Democratic) 23 votes William G.

Gillenwater (Progressive Republican) 2 votes O. A. Larrazolo (Republican) 2 votes Jose D. Sena (Republican) 1 vote[2]

Fall's term would end in March 1913, so he was up for re-election shortly after his initial term began.

The bitterness over Catron and Fall's alliance made Fall a target of the local Republican Party, as they believed Fall had not contributed sufficiently to their efforts to secure New Mexico's statehood, and was not worthy of their nomination. The selection of Catron and Fall also disappointed Hispanics, who had hoped that one of their own would be selected. Fall was also severely disliked by Democrats.

After various votes, the legislature re-elected Fall January 28, 1913. Governor McDonald, on the advice of his Democratic legal advisor, Summers Burkhart, said that the legislature's procedure had been illegal, and failed to sign the credentialing papers in an attempt to oust Fall by forcing a special session of the legislature and a new vote.^[57] The attempt failed; Fall won the special legislative election.^[58]

Two-term Democrat Furnifold Simmons was easily re-elected January 21, 1913. Simmons was a staunch segregationist, white supremacist and a leading perpetrator of the Wilmington insurrection of 1898.
