About the 1950 Senate elections

The Korean War began in June 1950, and Senator Joseph McCarthy's charges about communists in government had made anti-communism a central campaign issue. Republicans won 17 Senate races and Democrats 15, taking seats in California, Idaho, Illinois, Maryland, Pennsylvania and Utah. Democrats kept control by a narrow margin. Two Democratic leaders lost. In Illinois, Majority Leader Scott Lucas was beaten by Everett Dirksen. In Maryland, Millard Tydings, who had chaired the hearings that dismissed McCarthy's charges, lost to John Butler after a campaign that McCarthy's allies helped run. In California, Richard Nixon beat Helen Gahagan Douglas for an open seat. The closest race was in Connecticut, where William Benton beat Prescott Bush, father and grandfather of future presidents, by about 0.1 points in a special election. Herbert Lehman held New York for the Democrats, and Thomas Hennings Jr. unseated Forrest Donnell in Missouri.
