Johnson's opponents tried to agree on a single candidate who might gain majority support and defeat him, but failed, and he was elected on January 26 on the 54th ballot, with a margin of a single vote. Nashville erupted in rejoicing;[199][200] remarked Johnson, "Thank God for the vindication."[195]
Johnson's comeback garnered national attention, with the St. Louis Republican calling it "the most magnificent personal triumph which the history of American politics can show".[200] At his swearing-in in the Senate on March 5, 1875, he was greeted with flowers, and sworn in alongside Hamlin (his predecessor as vice president) by incumbent Vice President Henry Wilson (who as senator had voted for Johnson's ouster). Many Republicans ignored Senator Johnson, though some, such as Ohio's John Sherman (who had voted for conviction), shook his hand. Johnson remains the only former president to serve in the Senate. He spoke only once in the short session, on March 22 lambasting President Grant for his use of federal troops in support of Louisiana's Reconstruction government. The former president asked, "How far off is military despotism?"and concluded his speech, "may God bless this people and God save the Constitution".
