"look forward not back"

The problem for the Tories though is that they have been perceived (rightly or wrongly) as an anti-Scottish party. Rather than lessening that has probably been increased in the last couple of months as leading London Tories as well as UKIP made anti-Scottish statement after anti-Scottish statement. Sacrificing potential votes in Scotland to pick up more in southern England.

That won't be forgotten quickly by many Scots. Ruth Davidson and the other leaders of the Scottish Tories were apparently livid with the tactic but again many Scots have taken note that said Scottish leaders did not speak out openly against the said tactic. Davidson touched on it and criticised it only once when pressed in an interview. So I think that the idea that the Tories are anti-Scottish, which started in the Thatcher era, is going to be around for a while yet.
