Have you got a minute...?

It seems the reason the opinion polls got it so wrong in the run-up to the last general election is that they asked the wrong people!  The suggestion is that, although they asked people at random, they only asked people who were there - who were at home when they called or telephoned, or who were walking in the street or shopping mall when they were conducting their interviews.  And although it's rather non-PC to suggest it, prospective Conservative voters were more likely to be at work earning a crust and therefore not at home or wandering around, whereas those who were, were more likely to be prospective Labour voters. In other words, as it has been succinctly put - Labour voters are easier to find.  Interesting theory??
