At the State election in November 1830, the Jacksonian Democrats managed to defeat the combined Anti-Masons and National Republicans. Enos T. Throop was narrowly re-elected Governor, a large Jacksonian-Democratic majority was elected to the Assembly, and five of the nine State Senators elected were Jacksonian Democrats. The 54th New York State Legislature met from January 4 to April 26, 1831, at Albany, New York. The party strength in the Assembly as shown by the election for Speaker was: 91 for Jacksonian Democrat George R. Davis and 30 for Anti-Mason John C. Spencer.
Marcy resigned his seat on January 1, 1833, upon taking office as Governor of New York. The State Legislature held a special election to fill the vacancy in January 1833, and elected Silas Wright, Jr.
