Answer:
The progress of the Civil War, Public opinion, The economy
Step-by-step explanation:
The progress of the Civil War: The progress of the Civil War was a major factor that affected Lincoln's chance of reelection in 1864. If the Union army was making progress and winning battles, it would likely have improved Lincoln's chances of being reelected. On the other hand, if the Union army was suffering defeats and making little progress, it could have hurt Lincoln's chances of being reelected.
Public opinion: Public opinion was also a significant factor that affected Lincoln's chance of reelection in 1864. If the public was generally supportive of Lincoln and his policies, it would likely have improved his chances of being reelected. However, if the public was unhappy with Lincoln and his policies, it could have hurt his chances of being reelected.
The economy: The state of the economy was also a factor that could have affected Lincoln's chance of reelection in 1864. If the economy was strong and growing, it could have helped Lincoln's chances of being reelected. However, if the economy was struggling, it could have hurt his chances of being reelected.
