[329] He also was concerned because Texas had legalized slavery, which was an issue that could divide the Democrats during the 1836 election. Jackson recognized the Republic of Texas on the last full day of his presidency, March 3, 1837.[337]

Judicial appointments

Jackson appointed six justices to the Supreme Court.[338] Most were undistinguished. Jackson nominated Roger B. Taney in January 1835 to the Court in reward for his services, but the nomination failed to win Senate approval.[339] When Chief Justice Marshall died in 1835, Jackson nominated Taney for Chief Justice; he was confirmed by the new Senate,[340] serving as Chief Justice until 1864.[341] He was regarded with respect during his career on the bench, but he is most remembered for his decision in Dred Scott v. Sandford.[342]

States admitted to the Union
Two new states were admitted into the Union during Jackson's presidency: Arkansas (June 15, 1836)[343] and Michigan (January 26, 1837).[344] Both states increased Democratic power in Congress and helped Van Buren win the presidency in 1836, as new states tended to support the party that had done the most to admit them.
