Question

which factor contributed most to abraham lincoln’s victory? (not all factors described are accurate—see map for details.) a western territories supported abraham lincoln. b southern states were split between two democratic candidates. c border states sided with the north and supported abraham lincoln. d northern states had higher populations, giving them more electoral votes

Explanation:

To determine the factor contributing most to Lincoln's victory, we analyze each option:

• Option A: Western territories (like Utah, New Mexico) were neutral (territories, not supporting Lincoln as per the map's key), so A is incorrect.
• Option B: Southern states had two Democratic candidates (Douglas and Breckinridge) splitting the Democratic vote, but Lincoln's support was in the North. However, the main reason for electoral vote advantage was population - based electoral votes.
• Option C: Border states (like MO, KY) had mixed support (some for Douglas, some for others), not all siding with Lincoln, so C is incorrect.
• Option D: Northern states had higher populations. Electoral votes are based on population (House + Senate). Higher population in the North gave Lincoln more electoral votes (e.g., the Electoral College map shows Lincoln winning northern states with more electoral votes due to population). This is the key factor as electoral votes determine the presidency, and population - based electoral votes from the North were crucial.

Answer:

D. Northern states had higher populations, giving them more electoral votes
