United States presidential elections in Maryland  Following is a table of United States presidential elections in Maryland, ordered by year. Since its admission to statehood in 1788, Maryland has participated in every U.S. presidential election. Winners of the state are in bold. The election of 1860 was a complex realigning election in which the breakdown of the previous two-party alignment culminated in four parties each competing for influence in different parts of the country. The result of the election, with the victory of an ardent opponent of slavery, spurred the secession of eleven states and brought about the American Civil War. The election of 1824 was a complex realigning election following the collapse of the prevailing Democratic-Republican Party, resulting in four different candidates each claiming to carry the banner of the party, and competing for influence in different parts of the country. The election was the only one in history to be decided by the House of Representatives under the provisions of the Twelfth Amendment to the United States Constitution after no candidate secured a majority of the electoral vote. It was also the only presidential election in which the candidate who received a plurality of electoral votes (Andrew Jackson) did not become President, a source of great bitterness for Jackson and his supporters, who proclaimed the election of Adams a corrupt bargain. In the election of 1820, incumbent President James Monroe ran effectively unopposed, winning all 8 of Maryland's electoral votes, and all electoral votes nationwide except one vote in New Hampshire. To the extent that a popular vote was held, it was primarily directed to filling the office of Vice President.
