Abstract
This study examines the support for United Russia in 43 regional assembly elections which were conducted over the period from March 2008 to March 2011. In contrast to previous studies, which have tended to focus on the overall results of regional elections or just on the party-list votes, it provides a quantitative analysis of the votes for United Russia in the plural single member district contests. By widening the traditional focus on the aggregate results and party-list voting the study brings to light important variations in the patterns of United Russia's electoral domination of regional assemblies. The specific form of United Russia's domination depends on the configuration of regional elites and their strategies. Social and economic features of the regions have little impact on the degree and modes of United Russia's electoral domination, but influence the ability of regional leaders to ensure electoral mobilisation in the regions and this is more significant the higher the level of the election.
