It was Harold Wilson who said 'A week is a long time in politics'. How out of date that now sounds - 90 minutes is the new record after Nick Clegg's performance on Thursday night turned our traditional two-party democracy into a true three-party system.
In her analysis in the Sussex Express of 9 April, Susan King predicted that, of the six constituencies in the Express circulation area, five are likely to return an MP of the same party as last time, with only Eastbourne hanging in the balance. That was a reasonably fair assessment before last Thursday's first televised debate, but it's now looking a little less certain.
This was always a difficult election to call, because no-one could be quite sure how the MPs' expenses and cash for lobbying scandals would play out with the public. With the TV debate having firmly established three-party politics in this country, 'safe' seats are suddenly no longer so safe.
What irritated me about Susan King's otherwise fair analysis of the likely outcomes is that it carried an implicit overtone that it’s not worth voting unless you live in Eastbourne. (Credit incidentally to the Express for printing my complaint in this week's paper when they could have hidden behind a pre-election curfew on candidates' letters.)
But that's missing a very obvious point. Just as Manchester United would start at 0-0 in a cup tie against lowly opposition, so all the candidates in all the constituencies start at zero votes, and a rush of apathy or a last-minute reason to switch allegiance could yet produce some shock results.
With Nick Clegg's performance in the TV debate having changed the nature of the whole campaign, that indicates that, even if Charles Hendry represents Manchester United in our analogy of the Wealden constituency, the Lib Dems aren't a League Two side but from the Championship or even Premier League. And the thought of Wealden having a Lib Dem MP isn't quite so far-fetched as it was at 8.30pm last Thursday.
It would still be a major shock if we won this seat, but the Conservatives are no longer a shoo-in for victory. I have met people who have been very impressed with Nick's performance and who are voting Lib Dem having not originally expected to be. A few thousand of those and we really will have a shock result.
I'm also encouraged by Charles Hendry's own slogan 'Vote for Change'. I hope the Wealden voters take him literally, and vote to change the Wealden MP!
But even for those who believe Wealden won't change this time, there is more reason to vote Lib Dem than normal. The overall popular vote – the total votes cast for each party nationally – could have a strong moral role to play if no single party has an overall majority, so even in the supposedly ‘safe’ seats, there is more reason than usual to vote.
And after all, it’s only our corrupt voting system that renders so many votes apparently worthless in the first place. Hopefully this will be the last general election at which we use this discredited system, so there can never be an excuse again that voting Lib Dem - or any other party for that matter - is a wasted vote.
