Approximately two-thirds of the former Carrick, Cumnock and Doon Valley constituency was attached to a third of the former marginal Ayr seat to form this new Westminster constituency. Ayr is a mix of council estates and affluent middle-class areas. Added to the town was an expanse of left-wing former mining villages. On a local level, Carrick has been largely Labour-voting, with the Conservatives doing well in northern Girvan and Coylton. In Ayr the Conservatives have performed strongly in Scottish Parliamentary elections and on a local level, with Labour remaining dominant north of the river Ayr and in patches of east Ayr. Recent Westminister elections suggest that support for the Conservatives has grown considerably in the town of Ayr since the constituency's creation in 2005, whilst in local elections and in the Scottish Parliament the SNP have made inroads in Ayr North and in a number of council estates in Ayr East, such as Kincaidston, South Belmont and Forehill. Support for Labour in Cumnock at local elections has remained strong compared to elsewhere in the constituency.
