Throughout his presidency, Abraham Lincoln faced serious opposition to his political and wartime policies. Even in the North, the Civil War was so divisive and consumed so many lives and resources that it could hardly have been otherwise.  

Opposition to Lincoln naturally coalesced in the Democratic Party, whose candidate, Stephen Douglas, had won 44 percent of the free states' popular vote in the 1860 election.  

The strength of the opposition generally rose and fell in proportion to the North's effectiveness on the battlefield. The first manifestation of dissatisfaction with the war effort -- and by extension Lincoln -- came not from the Democrats, however, but from the Congress, which formed the Joint Committee on the Conduct of the War in December 1861 to investigate the poor Union showing at Bull Run and Ball's Bluff. Dominated by radical Republicans, the Joint Committee pushed the Lincoln administration toward a more aggressive engagement of the war, as well as toward emancipation.  

As might be expected from the party of "popular sovereignty," some Democrats believed that full-scale war to reinstate the Union was unjustified. This group came to be known as the Peace Democrats. Their more extreme elements were called "Copperheads."  

Whether of the "war" or "peace" faction, few Democrats believed the emancipation of the slaves was worth shedding Northern blood. Indeed, opposition to emancipation had long been party policy. In 1862, for example, virtually every Democrat in Congress voted against eliminating slavery in the District of Columbia and prohibiting it in the territories.  

Much of the opposition to emancipation came from the working poor, particularly Irish and German Catholic immigrants, who feared a massive migration of newly freed blacks to the North. Spurred by such sentiments, race riots erupted in several Northern cities in 1862.  

With the Emancipation Proclamation of January 1863, Lincoln clearly added the abolition of slavery to his war aims. This was far from universally accepted in the North. In both Indiana and Illinois, for example, the state legislatures passed laws calling for peace with the Confederacy and retraction of the "wicked, inhuman and unholy" proclamation.  

The North's difficulties in prosecuting the war led Lincoln, in September 1862, to suspend the writ of habeas corpus and impose martial law on those who interfered with recruitment or gave aid and comfort to the rebels. This breech of civil law, although constitutionally justified during times of crisis, gave the Democrats another opportunity to criticize Lincoln. Secretary of War Edwin Stanton enforced martial law vigorously, and many thousands -- most of them Southern sympathizers or Democrats -- were arrested.  

The Union's need for manpower led to the first compulsory draft in U.S. history. Enacted in 1863 to "encourage" enlistment, the draft further alienated many. Opposition was particularly strong among the Copperheads of Pennsylvania, Ohio, Indiana and Wisconsin, where federal troops had to be called out to enforce compliance with it.  

It must be noted that a man who was drafted could buy his way out for $300, about the equivalent of an unskilled laborer's annual income at that time. This feature added to the impression -- strongly held in parts of the Confederacy as well -- that this was a "rich man's war and a poor man's fight."  

The most significant resistance to the draft took place in New York City in the summer of 1863. A Democratic Party stronghold, New York had already seen several draft officials killed that year. In July a group of blacks were brought into the city, under police protection, to replace striking Irish longshoremen. At the same time, officials held a lottery drawing for the unpopular draft. The conjunction of the two events led to a four-day riot in which a number of black neighborhoods, draft offices and Protestant churches were destroyed and at least 105 people killed. It was not until several Union regiments arrived from Gettysburg that order could be restored.  

The most celebrated civil case of the Civil War also took place that year. It concerned Clement Vallandigham, an aspiring Democratic candidate for the governorship of Ohio. Apparently seeking to bolster his candidacy, Vallandigham defied a local military ban against "treasonous activities" and attacked Lincoln's policies, calling for negotiations to end the war and terming it "a war for the freedom of the blacks and the enslavement of the whites." Union soldiers subsequently broke into his house and arrested him.  

The legality of Vallandigham's arrest was immediately challenged by the Democrats and, indeed, some Republicans as well. Lincoln's response was to have him sent behind Confederate lines, where Vallandigham won the nomination. Making his way to Canada, he then carried out a boisterous, but unsuccessful, campaign.  

Despite the Union victories at Vicksburg and Gettysburg in 1863, Democratic "peace" candidates continued to play on the nation's misfortunes and racial sensitivities. Indeed, the mood of the North was such that Lincoln was convinced he would lose his re-election bid in November 1864.  

The Democratic candidate for president that year was General George McClellan, the man Lincoln had removed as commander of the Army of the Potomac two years earlier. McClellan's vice presidential candidate was a close ally of Vallandigham. Despite the hopes of the Democrats, however, McClellan refused to embrace the party's goal of negotiating an end to the war. Nonetheless, with victory at last within sight, Lincoln easily defeated McClellan in November, capturing every Northern state except New Jersey and Delaware.
