Sources of Split‐ticket Voting in the 1988 American Elections

Divided partisan control of the American national government is not a new phenomenon. Of the 41 presidents from Washington to Bush, 20 saw the House of Representatives under the control of the opposing party. While divided control of government is nothing new, however, its recent causes are. Before 1955, divided control was due to election reversals in the off year ‐ easily interpretable in terms of negative retrospective judgements or switched policy choices on the part of the electorate. After 1955, on the other hand, four of the seven presidents were elected with a House of Representatives controlled by the opposing party. By analysing data collected during the 1988 national elections, we distinguish between congressional and presidential ticket‐splitting and find their causes to be complex. It is caused, in part, by congressional incumbency and ballot formats, but wider social forces are also responsible for ticket‐splitting.
