The 1850 United States elections occurred part way through Whig President Millard Fillmore's term, during the Second Party System. Fillmore (1800-1874, served 1850-1853), had become 13th president on July 9, 1850, upon the death of his 12th brief predecessor, former U.S. Army General Zachary Taylor (1784-1850, served 1849-1850). Members of the 32nd United States Congress were also chosen in this election. Democrats kept control of both houses of the Congress of the United States.
In the House, Democrats won several seats from the Whigs, building on their continued control of the chamber. Several supporters of the Georgia Platform also won election as Unionists.[3]
In the Senate, Whigs lost a small number of seats to Democrats and the minor Free Soil Party. Democrats however retained a strong majority.[4]
