Labour have implemented social democratic ideas the best they can within the limited powers of the Welsh Assembly. As a result they were rewarded by the voters.

In Scotland the SNP were saved from their decade-long flirtation with the small state neolib model that caused such booms in Ireland and Estonia before their imploding. Thankfully the SNP never got to implement it and its social democratic wing has been ascendent once again. Scottish voters appear to be rewarding the SNP government's commitment to social spending, and you can understand why an unrepenting Scottish Labour Party has been drubbed.

I see this as a neutral result for Milliband. He has been rather ineffectual as leader and the Parliamentary Labour Party is suffering from an impoverished connection to Third Way ideology. The results are as much as he ought to have hoped for. The Scottish Parliament is not a council chamber and the Scots voted with a clear differentiation between Holyrood and Westminster, thus voting with Holyrood concerns in mind.

The Tories may celebrate SNP's drubbing of Labour but the Tories' celebration is surely Pyrrhic in nature. Scotland didn't vote for Tartan Tories in nats' clothing, but rather a broad social democratic position. In any case there is plenty of reason to believe that Labour will still do well in Scotland for general elections. The SNP don't tend to do well in Westminster elections which benefit Labour.
