First past the post is good for Labour and no one else

We do not have an obligation to vote for the Tories even if (under fptp) to fail to so results in a win for Labour. Since no such obligation exists it is very likely that fptp elections will result in victories for the Labour party. The Tory party can never be a problem with a fptp system because to be a problem means they must be in power. They are never in power in a fptp system so fptp is a perpetual monopoly for the Labour party. First past the post is always a win for Labour. Labour will always be in government until we get proportional representation. We can only get a non-Labour government with pr. With fptp it is impossible to be governed by anyone other than the Labour party.
