This is the 9th General Election in which I’ve been politically active. Let’s not think about how old that makes me! You can also add 4 Holyrood elections to that. I missed out on the first one because I was living in England and just about to give birth. That didn’t stop me running a committee room in Chesterfield on polling day, though. Nor did it stop me doing stuff for the Newark by-election that never was.

I’ve just been reflecting on all these campaigns and maybe I should write about each one individually at some point.

In each election, I have made sure that my effort is concentrated on target seats, even if that has meant travelling on a daily basis. The reason for that is that I’ve always been very aware that I know that what matters the day after polling day is the number of bums we have on seats in whatever legislature we’re in. I could not have it on my conscience to lose a key target by a few hundred votes while I’d concentrated on getting single figures in percentage terms in my home seat. Believe me I have seen that happen several times.

Building that momentum throughout the campaign needs extra help. I will be forever grateful to the wonderful people from across the East Midlands region who travelled several times a week to Chesterfield in 1997, or the Lothian people who travelled to help us in Edinburgh South in 2001 and 2005. Martin Garnett, who’s our candidate in Erewash again today, was part of that Chesterfield support team in 1997.

That help from outside ensures that can establish ourselves as the challenger, that we can out-campaign the opposition and put ourselves in a winning position. It means that we can talk to more voters and build that all-important impression of a growing campaign. Every single day of the campaign, extra people are needed to boost local capacity and sow the seeds of victory.

I would go as far as to say that if you are spending the majority of your campaigning time in a seat that is not a target, you are actually doing the party more harm than good.
