The 1864 United States presidential election was the 20th quadrennial presidential election. It was held on Tuesday, November 8, 1864. Near the end of the American Civil War, incumbent President Abraham Lincoln of the National Union Party easily defeated the Democratic nominee, former General George B. McClellan, by a wide margin of 212–21 in the electoral college, with 55% of the popular vote. For the election, the Republican Party and some Democrats created the National Union Party, especially to attract War Democrats. Despite some intra-party opposition from Salmon Chase and the Radical Republicans, Lincoln won his party's nomination at the 1864 National Union National Convention. Rather than re-nominate Vice President Hannibal Hamlin, the convention selected Andrew Johnson of Tennessee, a War Democrat, as Lincoln's running mate. John C. Frémont started to run as the nominee of the new Radical Democracy Party, which criticized Lincoln for being too moderate on the issue of racial equality, but Frémont withdrew from the race in September and that new party dissolved. The Democrats were divided between the Copperheads, who favored immediate peace with the Confederacy, and War Democrats, who supported the war. The 1864 Democratic National Convention nominated McClellan, a War Democrat, but adopted a platform advocating peace with the Confederacy, which McClellan rejected. The Confederacy seemed to have survival potential in summer 1864, but was visibly collapsing by election day in November. Despite his early fears of defeat, Lincoln won strong majorities in the popular and electoral vote, partly as a result of the recent Union victory at the Battle of Atlanta. As the Civil War was still raging, no electoral votes were counted from any of the eleven southern states that had joined the Confederate States of America. Lincoln's re-election ensured that he would preside over the successful conclusion of the Civil War. Lincoln's victory made him the first president to win re-election since Andrew Jackson in 1832, as well as the first Northern president to ever win re-election. Lincoln was assassinated less than two months into his second term, and he was succeeded by his vice president, Andrew Johnson, who favored quick restoration of the seceded states to the Union without protection for the former slaves. This led to conflict with the Republican-dominated Congress, culminating in his impeachment by the House of Representatives in 1868. He was acquitted in the Senate by one vote.
