When asked (today on Today, BBC Radio 4; but he'd said that before) about his earlier comment on the UKIP as full of " fruitcakes, loonies and closet racists", the Prime Minister of one of the world's oldest and most prestigous - some would even go as far as to say representative - democracy replied : "It’s no point
insulting a party who won the vote of a large number of people".
So this his how democratic logic works: stupid, unless supported by enough voters.
