What Factors Led to Zachary Taylor's Election as President in 1848

What factors led to Zachary Taylor's election as president in 1848?

A) His strong support for popular sovereignty made him a popular candidate in both Southern and Western states, particularly those that had recently been admitted to the Union.
B) With the Democrats split over the issue of slavery and the Free-Soil Party running a lackluster campaign, Taylor was able to capture an overwhelming majority of votes in the South.
C) His status as a Mexican War hero enabled Taylor to appeal to a wide range of voters, including those who had opposed the war, and his clearly articulated positions on a variety of issues other than slavery won over those who had doubts about him as a slaveholder.
D) The Whigs' running separate campaigns in the North and South enabled Taylor to appeal to many voters in a nation divided over the issue of slavery, and the inclusion of a third-party candidate drew votes away from his Democratic rival.
