Love and solidarity
you mean, people voted based on their manifesto rather than the sheffield victory rally? I agree.
I would suggest that most people make their decision to vote based on a number of factors, including (though not necessarily only) the manifesto; their perception of how likely the party is to implement its manifesto; their perception of the leader; their perception of the local candidate; their perception of how likely their preferred party/candidate is to win in their constituency; last minute shit that gets publicised immediately before the election.
I also suggest that these various factors will be of different proportional significance to different people (and possibly change for a given person over time) and that it is more-or-less impossible to judge the significance of the different factors (either for an individual or collectively) with any accuracy.
It's a complex business, this decision making.
