MikeB4: Here is a novel thought. The majority that voted to exit did so knowing what they were doing.
The fact that a number of surveys since the referendum have shown decreasing support for Brexit indicates that perhaps they didn't know. I think one even asked a number which way they voted and a sizeable chunk who voted for it don't support it anymore. Couple this with the outright lies from the pro-Brexit campaign and I think it is fair to say a lot didn't really know what they were voting for.
