Andrew Johnson (December 29, 1808 –  July 31, 1875) was the 17th president of the United States, serving from 1865 to 1869. He assumed the presidency as he was vice president at the time of the assassination of Abraham Lincoln. Johnson returned to Tennessee after his presidency and gained some vindication when he was elected to the Senate in 1875, making him the only former president to serve in the Senate. He pressed resolutions for constitutional amendments to provide for popular election of senators (then elected by state legislatures) and of the president (chosen by the Electoral College), and limiting the tenure of federal judges to 12 years. These were all defeated.A group of Democrats nominated Landon Carter Haynes to oppose Johnson as he sought a fifth term; the Whigs were so pleased with the internecine battle among the Democrats in the general election that they did not nominate a candidate of their own.
