Liberal Democrat Candidate Andrew George Canvassing In His Constituency

PORTHLEVEN, ENGLAND - APRIL 08: A dog barks as Liberal Democrat Andrew George canvasses in Porthleven on April 8, 2015 in Cornwall, England. The consistency of St Ives, which he has held since 1997 with a majority of 1,719, is seen as a key seat and is being targeted also by the Conservatives in the upcoming election. Prime Minister David Cameron has said that the six seats in the county of Cornwall are essential to achieve a Conservative majority when Britain goes to the polls on May 7.
