Premise: Maurice Anthony Foley (9 October 1925 – 8 February 2002) was a British Labour Party politician. He was elected as Member of Parliament (MP) for West Bromwich at a by-election in 1963, and represented the constituency until his resignation from the House of Commons in 1973. His successor in the resulting by-election was the future Speaker of the British House of Commons, Betty Boothroyd.
Hypothesis: Foley's constituency voted for him every election.
