Why are Tory politicians and the media chorus which supports them so slavishly, so loud in their abuse of Nicola Sturgeon, Alec Salmond and the SNP? Answer. Because they realise that the most likely election result is a McLabour government taking office with SNP support on motions of confidence and supply. That would be a government which because of the daft legislation for a five year term the Tories insisted on could hold power for years
That means the SNP have to be discredited and any Labour government which depends on them portrayed as illegitimate,dangerous and certain to break up the United Kingdom as the SNP use their power to extort home rule from Labour.
All balls. The only threat to national unity is the Tory refusal to offer the DevoMax offered to the Scots if they voted for unity as they did only to find CAMERON proposing to stop Scottish MPs voting on English issues.You can't treat Scots MPs as second class parliamentarians and if they choose to support a McLabour government then that government and that support aren't totally legitimate
Indeed since the SNP are further to the left than Labour that support should produce a more radical government. And it won't be one which splits up the UK because it's very existence depends on not doing so.
The Tories have to build up these horror stories (all eagerly amplified by a press chorus which is becoming desperate as the rich press owners become more frightened and throw independence,objectivity,and responsibility overboard to convert once great papers into propaganda sheets ) because they're all realising that their party hasn't improved its position on 2010 when they lost and took power because the LibDems sold out to them.
Next time they won't have enough friends to form a government.The LibDems aren't going to opt for Suicide Pact two and will be much fewer in number.UKIP won't have any MPs, the SNP won't touch them with Harry Lauder's stick and Ulster will want money big time.
Neo-Liberalism doesn't win friends.
