United States presidential elections in Connecticut
[1] One of the original Thirteen Colonies, Connecticut has participated in all sixty U.S. presidential elections since the American Revolution.During this period, Connecticut Republican Party chairman J. Henry Roraback built up a political machine which was "efficient, conservative, penurious, and in absolute control".After that, although the Republican Party won Connecticut several times in the presidential election, its advantage was no longer as significant as it had previously been.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.[56] 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.
