WOW!

With less than one week until election day, polls are suggesting the SNP could win every single seat in Scotland.

Is this really feasible? Probably not, but even to become the largest party in Scotland at Westminster would be an unbelievable result for the SNP.

It is now at the stage where if the SNP don't win 40 of the 59 seats it will be a disappointment.

Even though that would be more than double of what last year would have been seen as a spectacular success.

Why has this happened when the independence question was settled by the people less than a year ago?

Why has Labour not been unable to build on the successful no vote it so vigorously campaigned for?

People voted no but were largely unimpressed by the parties and the politicians leading the campaign.

People voted yes out of enthusiasm, hope and expectation, whereas the no vote for many was prompted by the fear of taking too much of a risk.

The SNP and others in the yes campaign managed to energise not only their own supporters but recruit a whole new wave of people, many of whom have since become active in campaigning.

The General Election couldn't come quickly enough for those who signed up to the SNP in the wake of the referendum and their enthusiasm hasn't had time to fade yet or to be disappointed.

The 45% was obviously not enough to win a referendum, but if that 45% or even 40% can be persuaded to keep going and vote for the main pro independence party in a first past the post General Election then it will deliver majorities around the country.

The campaign for the General Election began for the SNP immediately the referendum was over.

When Alex Salmond announced "the dream shall never die" as he stepped down, Nicola Sturgeon's first test on the horizon was the General Election.

The momentum it built up with a surge in membership and the Nicola Sturgeon factor has created excitement among a political party's supporters never seen here before.

Meanwhile Labour went into a period of turmoil. Johann Lamont's resignation exposed divisions and created animosity and distrust of Labour at a UK level.

Jim Murphy has, in a short time, created a policy agenda and given the party a message to campaign on once more but the election may have come too soon for him.

He has been left with a task of turning round the party in six months from a crisis that has been more than six years in the making.

The contrast between the two couldn't be more stark and the opinion polls reflect that.

But like they say, a week is a long time in politics.
