Answer: Andrew Jackson won reelection as president in 1832.
Details:
Andrew Jackson was the Democratic candidate and was the incumbent, having first been elected to the presidency in 1828. Henry Clay was the Republican candidate defeated by Jackson in 1832.
Let's back up a step futher for context. In the presidential election of 1824, Andrew Jackson won the most popular votes (43%) and won the most electoral votes also. But since no one had attained a majority of electoral votes, the decision was given to the US House of Representatives, which named John Quincy Adams as president. Jackson accused Adams and Speaker of the House Henry Clay of what he called "a corrupt bargain."
Four years later, when Jackson ran for president again in 1828, he pulled no punches. It was a nasty, dirty campaign ... and set a precedent for the sort of negative politics we've been seeing ever since.
In 1828, Jackson won 56% of the popular vote and got 68% of the Electoral College votes. Jackson remained the popular choice in 1832, winning 54% of the popular vote and 77% of the Electoral College votes.
