1) The undecided are swayed by the positivity of 'yes' on the form and the momentousness of the chance to make history 2) 'No' voters are much less vocal and less likely to divulge their preference because of being seen as unpatriotic Whichever is the biggest factor in the undecided vote will win it for me. I've gone for yes at the bookies
It's just my opinion but the "No" voters seem to be showing a lot more class than the "Yes" voters who can't wait to open their mouths to tell everyone how they're voting.
If I was Scottish I'd vote yes. From a selfish view I hope it's no. I think a lot of it is the nature of the vote- people who want things to remain the same are bound to be less volatile. But I agree that some of the stuff I've seen seems to be aggressive and lack class in the yes campaign. I really dislike Salmond and the SNP
