Which political faction would have most likely supported President John Tylers pro-annexation stance in regard to Texas?

President John Tyler's pro-annexation stance regarding Texas would have most likely been supported by the Democratic Party, particularly its more expansionist and Southern factions. These groups favored Manifest Destiny and the expansion of slaveholding territory, viewing the annexation of Texas as a means to enhance the United States' land and influence. Additionally, some members of the Whig Party, who were sympathetic to expansion, may have aligned with Tyler's views despite his own affiliation with the party.
