The Tennessee senator stated that "all men are created equal" from the Declaration of Independence did not apply to African Americans, since the Constitution of Illinois contained that phrase—and that document barred voting by African Americans.[76][77] Johnson, by this time, was a wealthy man who owned 14 slaves.[78][79]
Johnson hoped that he would be a compromise candidate for the presidential nomination as the Democratic Party tore itself apart over the slavery question. Busy with the Homestead Bill during the 1860 Democratic National Convention in Charleston, South Carolina, he sent two of his sons and his chief political adviser to represent his interests in the backroom deal-making. The convention deadlocked, with no candidate able to gain the required two-thirds vote, but the sides were too far apart to consider Johnson as a compromise. The party split, with Northerners backing Illinois Senator Stephen Douglas while Southerners, including Johnson, supported Vice President Breckinridge for president. With former Tennessee senator John Bell running a fourth-party candidacy and further dividing the vote, the Republican Party elected its first president, former Illinois representative Abraham Lincoln. The election of Lincoln, known to be against the spread of slavery, was unacceptable to many in the South.
