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 ran as the nominee of the Radical Democracy Party, which criticized Lincoln for being too moderate on the issue of racial equality, but Frémont withdrew from the race in September. 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.
