Which group opposed war with mexico?

a) republicans

b) democrats

c) whigs

d) federalists

whigs

The correct answer is C. The Whigs opposed the war with Mexico.

Explanation:

In the United States, which was increasingly divided, war was a partisan issue. Most of the Whigs in the north and south of the country were opposed to the war, most Democrats supported it. The Southern Democrats, who encouraged themselves with the doctrine of manifest destiny, supported the war with the hope of adding territory to the south, which would be territory where slavery would be legal, and thus avoid being outnumbered numerically by the growing population of the north.
