Over at the Daily Mail, Lib Dem shadow chancellor Vince Cable takes a look at the hard reality of being a politician during a gruelling election campaign. Here’s an excerpt:

Mostly elections are a punishing schedule of interviews, meetings, encounters with voters and lots of travel. I am often asked if I enjoy it. It seems ungracious to say no but enjoy is not the word I would choose. Perhaps there is a parallel with extreme sports, the same combination of adrenaline and the knowledge that disaster is potentially just seconds away.

Vince then gives us an insight into his last week’s campaign trail activities:

Wednesday is an upward change of gear: two big speeches in London and a trip to Cornwall. After standing in front of 2,000 business directors in a packed Royal Albert Hall I have to dash off to Gatwick. An hour later I am in a Cornish resort to support our candidate in South East Cornwall. Reports are coming in of Gordon’s Gaffe. I suspect the crucial economic debate may be lost in the blizzard.

But then I talk to our candidate in Plymouth: she is an impressive surgeon who reminds us that there are still fine people that see politics as public service. Back in London, I end my day speaking to a packed audience assembled by Operation Black Vote in Methodist Central Hall. News reaches me that previous speakers – Harriet Harman and George Osborne – have been booed.

And as for the final week of the campaign – it:

… seems to cover every corner of Britain and requires a Tardis. Better to dream of Friday when it’s all over.
