We don’t know all the details of the demographics of Conservative Party members for sure because the party does not publish an exact breakdown but the best estimates we have are provided by Queen Mary University of London. Their estimates tell us: Almost three quarters of the membership are male, over 60 per cent of members are over 55, more than three quarters of members are Leave voters, and over 40 per cent of members live in the South East. Tim Bale, lead author of Queen Mary’s research report into political memberships, posited that older members may resent Sunak for being “preternaturally young and smooth”, while men may be drawn to Truss for the same reason many supported Thatcher — “they rather like a disciplinarian governess type”.
