Yellow Dog Democrats was a political term applied to voters in the Southern United States who voted solely for Democratic candidates, with the term commencing in the late 19th century. Due to Republican president Abraham Lincoln`s leading the Union against the Confederacy, these voters would allegedly "vote for a yellow dog before they would vote for any Republican". The term is now more generally applied to refer to any Democrat who will vote a straight Party ticket under any circumstances.
