A higher number of representative per citizen ten to counter this effect. When an election as a small number of people who vote, their vote as more individual power, which mean, the people who end up being elected has more responsibility toward the voter, since each of them can significantly impact his chance of being re-elected.

Election with a big voter pool tend, on the other end, to blur the individual for the benefit of identifiable group with clear political line. The result of this is that, the representative get elected because they are part of this group, not truly because of his own idea (although there is exception). Due to this, it is their expected behavior that they will be faithful to the line of the party.

We have more representatives in the Parliament than France for a quarter of the population, everybody is voting what the party leader decides. Hard facts, not anecdotal evidence.
