On this day, Lewis Cass won the Democratic Party’s endorsement for President, but he would eventually lose the election due to a split vote among the Democrats. Martin Van Buren (who ran under the banner of the Free Soil Party) siphoned off enough anti-slavery Democratic votes to allow Zachary Taylor, the Whig Candidate, to win.
