Gerald Warner spells out the future for any remaining Conservatives in the party:
Cameron’s move was classically Blairite. Tony Blair made no secret of his disdain, amounting to loathing, for the Labour Party, from whose culture he remained always aloof. That is similarly the case with Dave: he is not comfortable with Tories or Toryism, as this pre-emptive strike demonstrated. The need to cosy up to the Liberal Democrats energised Dave to do what he wanted to do anyway: eliminate grassroots Conservatives and Conservatism from the Conservative Party.
