The 'United States presidential election of 1848' was an open race.
President James Polk, having achieved virtually all of his objectives in one term and suffering from declining health that would take his life less than four months after leaving office, kept his promise not to seek re-election.
The Whigs in 1846-47 had focused all their energies on condemning Polk's war policies. They had to quickly reverse course. In February 1848 Polk surprised everyone with the
Treaty of Guadalupe Hidalgo that ended the war and gave the U.S. vast new territories (including California and most of Arizona and New Mexico). The Whigs in the Senate voted 2-1 to approve the treaty. Then in the summer the Whigs nominated the hero of the war,
Zachary Taylor. While he did promise no more future wars, he did not condemn the war or criticize Polk, and Whigs had to follow his lead. They shifted their attention to the new issue of whether slavery could be banned from the new territories. The choice of Taylor was almost in desperation--he was not clearly committed to Whig principles, but he was popular for leading the war effort. The Democrats had a record of victory, peace, prosperity, and the acquisition of both Oregon and the Southwest; they appeared almost certain winners unless the Whigs picked Taylor. "It is doubtful whether we can beat the scoundrels next Pres. Election," complained one Whig leader (John Defrees). "The war will have been ended -- and an immense acquisition of Land will be pointed to as the result of Democracy -- the Land stealing, even among our best Christians, is popular!" [Holt p. 312] Taylor's victory made him one of only two Whigs to be elected President before the party ceased to exist in the 1850's, the other Whig to be elected President was
William Henry Harrison, who had also been a general and war hero.
Nominations

"Grand Presidential sweep-stakes" - political cartoon of the three main candidates
Whig Party nomination

Taylor/Fillmore
Mexican-American War General
Zachary Taylor of
Louisiana, spurred by his successes on the battlefield but who had never voted in an election himself, was openly courted by both the
Democratic and
Whig parties. Taylor ultimately declared himself a Whig, and easily took their nomination, receiving 171 delegate votes to defeat
Henry Clay,
Winfield Scott,
Daniel Webster and others. After Webster turned down the vice presidential candidacy,
Millard Fillmore received the party's nomination for
Vice President.
Democratic Party nomination
The
Democrats countered by nominating
Lewis Cass, who had served as Governor and Senator for
Michigan, as well as
Secretary of War under
Andrew Jackson, and from
1836-
1842 as
ambassador to
France. General
William Orlando Butler was nominated to join Cass on the ticket, garnering 169 delegate votes to defeat five other candidates, including future
Vice President William Rufus deVane King and future
Confederate President
Jefferson Davis. The Democrats chose a platform that remained silent on slavery, and with Cass suspected of pro-slavery leanings, many anti-slavery Democrats walked out of the
Baltimore convention to begin the Free Soil party.

Cass/Butler
Free Soil Party nomination

Van Buren/Adams
A third party, the
Free Soil Party, was organized for the
1848 election to oppose further expansion of
slavery into the western territories. Led by
Salmon P. Chase and
John P. Hale, former President
Martin Van Buren defeated
John Parker Hale by a 154-129 delegate count to capture their nomination, while
Charles Francis Adams, the son and grandson of two other presidents, was chosen as the vice presidential nominee.
General election
Campaign
With Taylor remaining vague on the issues, the campaign was dominated by personalities and personal attacks, with the Democrats calling Taylor vulgar, uneducated, cruel and greedy, and the Whigs attacking Cass for graft and dishonesty. The division of the Democrats over slavery allowed Taylor to dominate the Northeast.
Results
With the exception of
South Carolina, which left the selection of electors to its legislature, the election of
1848 marked the first time in which every state in the union voted for President and Vice President on the same day:
November 7,
1848.
Taylor won election over
Cass, capturing 163 of the 290 electoral votes cast. However, Taylor won barely more than 47% of the popular vote, and had the Free-Soil Party not diverted votes from the Democratic ticket, Cass might well have won the election.

★ ''
Massachusetts law provided that the state legislature would choose the Electors if no slate of Electors could command a majority of voters statewide. In 1848, this provision was triggered.''
