Question

All of the following groups resisted or were skeptical about, in their own way, American westward expansion EXCEPT Abolitionists seeking to halt the spread of slavery The Tyler and Polk administrations Native American tribes of the Southeast Whigs focused on urbanization

Answer 1

The Tyler and Polk administrations

Both administrations strongly supported American westward expansion.

John Tyler pressed for the annexation of Texas as a slave state during his administration (1841-45) and at the end of it, he signed a Texas annexation bill into law, which was admitted as a state in the first year of Polk's presidency.

James K. Polk, who ruled from 1845 to 1849, also supported American expansion to the point he led the U.S. into the Mexican-American War (1846-48) in which the U.S. gained what is today California and much of the present-day Southwest.
