Question

why were southerners more likely than northerners to support the mexican-american war?
○ southerners supported manifest destiny, while northerners did not.
○ states that formed from the new territory would likely allow slavery.
○ more southerners belonged to the whig party and supported the war.
○ southerners lived near the border and were concerned about attacks.

Explanation:

• Analyze each option:
• First option: Both regions generally supported Manifest Destiny, so this is incorrect.
• Second option: The Mexican - American War's new territories (like Texas) were likely to be slave states. Southerners, with economic interests in slavery, supported the war to gain such territories. Northerners, opposing slavery's expansion, were less supportive. This makes sense.
• Third option: Whigs (including many Northerners) opposed the war, so this is wrong.
• Fourth option: Proximity to the border and fear of attacks wasn't the main reason for Southern support; the slavery - related territorial gain was more crucial.

Answer:

B. States that formed from the new territory would likely allow slavery.
