At the moment, the discussion seems to assume that those policies would always be those of the SNP. The forthcoming referendum should be on independence, not on SNP policies. That is what general elections are for.
The problem is that the SNP seem to be claiming ownership of the whole process. It was evident on the TV last night on the televised debate where she claimed that if Scotland wanted to get rid of nukes on the clyde the only way it could guarantee it was to vote independence, when in reality that still assumes one of the other parties don't get in - labour for instance don't seem overly bothered by moving them.
The major issue is that no-one has any real figures to throw around as no-one has done it before. What's more, the pro-seperatist folk throw around emotions and "clearly this means this" and no hard evidence, while the opposition point out the flaws and look anti-scotland. It's an insane arrangement and a complete waste of time and effort.
You don't really believe that do you?
It clearly does sit uneasy with some, and there are major questions on where they'd put them without, but there are a few sites that could be used/adopted.
