David Mundell is a tough nut to crack. He has been the Conservatives’ only Scottish member of Parliament since 2005, fending off the SNP and Labour for years. It looks like he won't be alone for long, as Ruth Davidson is busy reviving the party’s fortunes north of Hadrian’s Wall.

Ms Davidson robbed the SNP of its majority in Holyrood last year, and she's not finished there. Polls now suggest she could take several seats off the Nicola Sturgeon's party when Scots vote in next month's general election. The cybernat vitriol would have you think that "Tory" is a swearword in Scotland, so how can they be on their way back?

Simply, the nationalist magic is starting to wear off. Nicola Sturgeon wants to gloss over her thin list of accomplishments, but the public is realising that she has little to boast of beyond agitating for independence.
