In reply to Donnie:
We're not smart enough for any referendum. That's not a reflection on us as a country, just the nature of referendums. How much independent research do you think people did before voting at the AV referendum? I reckon an average of about 5 minutes, because most people would have done none. People voted no because they didn't like Nick Clegg and because that's the way the wind was blowing at the time.
When you put a deeply complicated question to the country people seem to approach it as if they're answering a survey about what cheese they like. "I'm out, bloody europe meddling in our business. Keep the pound!" or "I'm voting to stay in because otherwise no one will buy our stuff". An utterly, utterly useless way to make policy.
The only thing that surprises me with referendums is the low turn out, everyone's always an expert in this country with wild, uninformed opinions about all and sundry that they're dying to tell everyone about. Yet no one turns up when they're asked.
