Voters are to the right of the Labour party

There is an argument which goes that since the voters are in the main illiberal and ill-informed then to have democracy is not a good idea and this (so the argument goes) supports fptp. The voters, it is implied, can't really be trusted with democracy and as a consequence of this first-past-the-post is a suitable compromise because there is some democracy but not entire democracy.

The flaw in this argument is that fptp does not eradicate democracy entirely (even if that is a good thing which I have not accepted) we still get a government derived from the election and the choice is narrowed to a two-party system. Governments formed by fptp are not guaranteed to be liberal in fact more often then not at least in recent times it is the Labour party who have been successful. This means that unless the general body of voters is to the left of the Labour party fptp is delivering Labour governments which are to the left of the typical voter.

The first-past-the-post system does not impose liberalism on the people because there remains some choice even if that choice is reduced to a two-party split. Only if Labour are to the right of the general voter would it be possible to argue that fptp is imposing liberalism on an unwilling people. If that is not the case then fptp is reducing choice and limiting a liberal (to the right of Labour) electorate to choosing the least bad of Labour and the Tories. If voters are to the right of Labour then pr is to be preferred because under fptp Labour generally do well.

Voters are to the right of Labour but with fptp Labour generally get in which means fptp governments are to the left of pr governments.
