The Scottish parliamentary and local elections of 2007 were significant for two key reasons: the SNP was brought to power for the first time in its history, posing a fundamental challenge to the 300-year Scottish-English Union; and the local elections used the Single Transferable Vote - the first time such an electoral system has been used in Great Britain since 1945.This book explores the significance of these two developments, asking whether they herald a revolutionary break with the past or simply mark a continuing evolution of existing patterns of Scottish politics. It uses a unique source of evidence - representative high quality annual sample surveys of the Scottish public that since 1999 have regularly measured how people in Scotland have reacted to devolution and how they have behaved in elections.Readers will gain an unparalleled insight into the identities, attitudes and electoral behaviour of people in Scotland during the first decade of devolution.
