Oh, come on Bridge, anybody with any principles wouldn't want to get anywhere near Westminster. The constituency candidate lists are stage managed from party central offices, if you get elected you are nailed into line by the Whips, and any real power in the majority party is vested in a minority cabal around the PM, the full cabinet are cowed into submission by fear of reshuffles; and backbenchers are just cannon fodder, only valued when they have to troop through the lobbies in support of unpopular legislation. They are despised by the civil servants they work with.
As for the electorate; 35% won't turn out, they will find something better to do, like bath the dog or watch paint dry. 40% will already know how they are voting based on party allegiance - they probably won't even read the candidate's name on the ballot paper, let alone learn what they look like. 10% will vote negatively, finding reasons NOT to support one party or another, 7% will vote the way their daily paper tells them, 6% will vote for the party that they think will make them better off, and the remainder will vote for a fringe party or spoil their ballot.
As Churchill said "Democracy is the worst form of Government,- until you consider the alternatives".
