It's all up for grabs say election candidates in the southwest along the A303/A30 corridor.
With everything so changeable, the potential for established MPs to lose their seats is high. In the Times article Tory MP for neighbouring Somerton and Frome constituency insists 'its all up for grabs'. Looking at previous election data is certainly interesting reading and the express article mentions seats to watch and see which way the swing is going.
Here in South West Wiltshire, the last Liberal Democrat MP was elected in the former Westbury constituency in the 1920's, but elections in recent years have shown seats can and do swing. Prior to the 1920's the constituency swung between Liberal and Conservative for a hundred years.
