Yes. I am suggesting exactly that. Or at least a random sample of a few hundred POSTAL voters.
If that shows that 50% of the postal vorters are in fact not valid, then its time to change the law of postal voting.
Gaming the system is very much the way the hard Left and certain ethnic groups who consder democracy the enemy, operate.
Since I moved back to my house I have had not one, but two letters inviting me to regsiter who is living here. No checks are made whatsoever.
I could easily have filled it up with imaginary students or an extended family.
All you seem to need are valid NI numbers.
But no one checks. Many students vote at home and in their university towns.
1000 labour activists registered as living in the area but who actually live elsewhere, and who need not even attend the polling station is all it takes with such a low turnout
