Multi-level voting and party competition in vertically simultaneous elections: the case of Ukraine

Vertically simultaneous elections to state-wide and regional legislatures provide us with a naturally occurring experiment in which to examine regionalism and multi-level voting. We examine the 2006 vertically and horizontally simultaneous state-wide and regional elections in Ukraine to determine how the internal dynamics of regionalism within a state account for the dissimilarity of voting behavior across electoral levels. Drawing on the party competition literature, we demonstrate that variations in both supply (parties) and demand (voters) produce considerable dissimilarity between regional and state results, with lower levels of consolidation and greater fractionalization at the regional level. We show that political cleavages operate differently across levels, that regional distinctiveness rather than regional authority better predicts first order-ness in regional elections, and that voters display varying tolerance for polarization at the regional and state level.
