The 1840 Democratic National Convention was held in Baltimore, Maryland, from May 5 to May 6. The Democratic Party re-nominated President Martin Van Buren by acclamation, but failed to select a nominee for vice president. Van Buren is the only major party presidential nominee since the ratification of the Twelfth Amendment to seek election without a running mate. Dragged down by the unpopularity of the Panic of 1837, Van Buren was defeated by the Whig Party's ticket in the 1840 presidential election.[1]
