Seeing me hesitate, one of the returning offices called from behind me to put the papers into the appropriately labelled box. Well yes, I'd worked that out, but I had to hold the papers up nearer the window to tell the "white" from the grey!
Regarding the AV versus FPTP system, I settled on voting "Yes". In the past, I have always been swayed by the, "It'll let the extremists in," argument and hence had remained ambivalent until recently, but I am no longer convinced that is a danger.
The leaflet we got through the door the other week explained the proposed system clearly, but I really wish I had seen this before I voted.
The difference between the FPTP and the AV system, explained using cats. :)
PS To those who are saying we've only ever had two referendums (or referenda, if you prefer that plural), we have had more in Wales and in fact had one just recently, the results of which have given the Welsh Assembly Government more power to make their own laws without constantly having to run to Westminster to get it okayed.
