Just an interesting statistic from this page so far -
24/178 (13%) OUT voters felt the need to justify or elaborate on their answer e.g. Bar 2 people, everyone I know of any age or background is an out and none of us are racist
15/251 (6%) IN voters felt the need to justify or elaborate on their answer e.g. Most people we know (of our age at least) are IN
I've got a feeling that OUT voters are far more vocal in polls etc than IN voters and that this will be reflected on the day with IN quietly pipping OUT to the post.
Either that or there is some correlation between being an OUT voter and not being able to follow simple rules :)
