Andrew Johnson didn't exactly "decide" to be President. John was President Lincoln's Vice-President, and the office was thrust upon him when Lincoln was assassinated in April 1865, because the Vice-President is first in line of succession.
Johnson probably liked wielding power, but had burned his bridges with both the Republican Party and his own National Union Party. Although the Southern Democrats expressed some support for him, they weren't willing to accept any of the Lincoln policies Johnson supported, so he was a dead horse candidate for reelection to the Presidency.
Johnson also made an unsuccessful attempt to run for Senate in the 1868 election, and for the House of Representatives in the 1872 election. The State of Tennessee finally elected him to serve as a Senator from Tennessee in the 1874 election, but Johnson died of a stroke in July 1875, so he was only in office a few months.
