50% SNP support on a 50% turnout amounts to 25% of the electorate.
30% YES support on a 80% turnout amounts to 24% of the electorate.
24% of the YES electorate as a % of the 25% SNP electorate amounts to 96%.
So either 96% of those who voted for the SNP will vote YES
OR
a significant % of those who didn't vote for the SNP will vote YES.
The second case seems more likely.
A % of the SNP vote came from NO voters.
A % of the non SNP vote came from YES voters.
Comparing the 25% SNP and 24% YES figures, the SNP NO and non-SNP YES seem to cancel each other out.
The latest Panelbase poll shows:
YES 35%
NO 43%
Undecided 20%
11 months before the referendum, a swing of less than 5% is needed for a YES vote.
http://wingsoverscotland.com/the-gnats-chuff/To answer the main question again,
YES, Scottish independence will be a 'good' thing for the vast majority of the people of Scotland.
The minority that will be worse off will include the likes of Alistair Darling, Anas Sarwar and other Labour, Liberal Democrat and Tory Westminster MPs.
Also worse off will be the various 'Lords' from Scotland who only have to turn up at the House of Lords to claim expenses of £300 PER DAY.
