# 1928 United States Senate elections

The 1928 United States Senate elections were elections that coincided with the presidential election of Republican Herbert Hoover. The 32 seats of Class 1 were contested in regular elections, and special elections were held to fill vacancies. The strong economy helped the Republicans to gain seven seats from the Democrats.
Senate Majority leader, Republican Charles Curtis of Kansas, was not up for election this cycle, but he was elected U.S. Vice President. He resigned March 3, 1929, so his seat was vacant at the beginning of the next Congress until April 1, 1929, when a Republican was appointed to continue the term.

First-term Democrat Woodbridge N. Ferris died March 23, 1928.
On March 31, 1928, Governor Fred W. Green appointed 44-year-old Republican Arthur H. Vandenberg to fill the vacancy, pending a special election. Green considered resigning so he could be appointed to the vacancy. He also considered several other candidates, including former governors Albert Sleeper and Chase Osborn. In addition, Green considered Representative Joseph W. Fordney, who would have been a placeholder until the election for the remainder of Ferris' term. Green finally decided upon Vandenberg, who immediately declared his intention to stand for election to both the short, unexpired term and the full six-year term. Both the special and the general elections were held the same day, November 6, 1928.
