ANSWER
President James Buchanan (a Pennsylvanian) endorsed the Dred Scott decision and supported the Lecompton Constitution. President Franklin Pierce (from New Hampshire) signed the Kansas-Nebraska Act, tried to annex Cuba, and supported the Lecompton Constitution. Massachusetts Senator Daniel Webster was roundly denounced for endorsing the Compromise of 1850, and Illinois Senator Stephen Douglas was harshly criticized for introducing the Kansas-Nebraska Act.
