^It is possible to know how many older voters have died and estimate the proportion of those that were 'leave' voters and know how many young people have joined the voter's list since a specific date and estimate (by polling them) how many feel an opportunity has been taken away from them by Brexit^
But it’s all guesswork aka smoke and mirrors PippaZ
Judging by the demographic of a site called Gransnet you might expect all of us “oldies ” to have been Leave voters - do you include yourself? So you cannot speak for others. Your use of the word estimate says it all.
Don't answer that, as we are still (despite exit polls/you give polls/pundits/armchair experts) able to enjoy a secret ballot in this country so speculation as to how many died, whether they voted Leave or Remain, indeed whether they voted at all (DH didn’t , he was in hospital and we had left it too late to organise a postal vote)and lots of other imponderables etc etc etc
Which brings me back precisely to asking “How long is a piece of string?”
So, psephology uses historical voting data, public opinion polls, campaign finance information, and similar statistical data. Psephology is a division of political science that deals with the examination as well as the statistical analysis of elections and polls.
You, on the other hand, think the saying "how long is a piece of string" and "it's all smoke and mirrors" wins an argument.
Argument: a reason or set of reasons given in support of an idea, action or theory.
Your argument is unfounded and offers only your opinion and some catchphrases as "facts": they aren't. There is no deductive reasoning - which is there in the psephologist's analysis which makes yours a very weak argument.
Now this will not stop you from holding those views, nor should it, but you are pushing a boulder uphill in your effort to convince me or anyone else, other than those who already want to see it from your perspective, that you are making any actual, valid point.
