But this isn't the case. In every representative democracy around the world, including ours, the bedrock principle is that elected politicians "vote their conscience", i.e. they are not bound by what they said they'll do if elected. So in practice you can't assume that what you voted for will be put into action. If anything, the track record on that is pretty poor.
