I think that the rôle of psephologists can be very important.
That is especially the case if they are psephologists and saying something that we may not like to hear.
Any psephologist will tell us that a person's decision whether to vote or to stay at home is affected by a whole range of issues.
This merely proves that politicians, like pollsters and psephologists cannot foretell the swings and the roundabouts.
The next few years will be a psephologist's dream.
The psephologists tell us that the larger the constituency the larger the swing.
Clever psephologists tell us that, in the main, at elections people hardly ever vote for anyone at all—they vote against people.
The psephologists, all of whom seem to be male, have decreed that the swing to female candidates at the election was greater than that to male candidates.
