Corbyn is evidence of how too much democracy can be a bad thing. Here we have an important role, leader of the opposition, decided by a very small minority of the country. There isn't mass participation in party politics in the UK so the small amount of people who do get involved have a disproportionate influence which is made worse by the fact we're talking about a specific demographic that are unrepresentative of the wider country. Combine all of that and you end up with Corbyn.

Of course the parties have protection against this by having leadership shortlists decided by their Parliamentary party. The MPs typically represent a wider section of the country than their membership by virtue of the fact they're elected by ordinary voters in larger numbers. It also ensures that the party leaders do have substianial backing from their MPs. The stupidest thing Labour have done in years was nominating Corbyn 'to widen the debate'.

In short. Democracy is rubbish when participation is so low. It means fringe candidates voted for by unrepresentative, and motivated, voters do very well at the expense of everyone else.
