many more voted "no"
Not sure how much you've been watching the campaign, but it's pretty clear that a huge chunk of those people only voted "no" because of the panicky concession promises that the party leaders in Westminster made a week before the vote, when it looked like the "Yes" campaign was making ground.
It's only nationalism that inflates the "yes" numbers.
It's also about a hatred for Westminster politics, which of course many people south of the border share as well.
