How did Lincoln win re-election even though he was opposed?

At the time of the re-election, the Civil War in the United States was still going on. Although, it was about to end in the next year. Even though many citizens had suffered through the Civil War, they realized the need for it.

In 1864 when Lincoln had already been president for four years, he actually easily won the re-election. One way he did this was by being apart of the National Union Party which was now made up of republicans and several democrats.

Since this party took away several democrats, there were not as many democrats to vote for the Democratic candidate for president. This was George McClellan. Lincoln easily won the electoral votes. However, he only slightly won the popular vote with 55%.
