Throwing Jim Murphy under a bus to shore up the English marginal vote. Might be a good strategic decision. For him at least.
This isn't throwing him under a bus. At all. I don't think people are understanding what's currently going on?
Labour have held scottish seats for *years* on the basis of being the anti-tory party. If Ed comes out now and says he'll work with the SNP to keep the Tories out of government, he can write off every single scottish seat, today. It would instantly legitimise everything the SNP have said, and makes it completely safe for every Scottish labour voter to vote SNP I stead of labour.
Of course post election he will change his tune. But right now the only hope labour have of keeping any seats in Scotland is by focussing on labour being the only major party that can form a government, and that voting SNP gives the Tories a change at power.
He literally has no other option currently if labour want to hold Scottish seats.
