Don't Forget, Millions of Potential Voters Still Don't Know

I think we can now officially call this the 'stalemate election'.

Even the introduction of Boris has failed to break the shackles. The two main parties have been wheeling out all their 'big guns' in the last couple of weeks to no effect. And who do they have left? Does anyone at Tory HQ even have the mobile number for John Selwyn Gummer?

Of course the big problem for the Conservatives and Labour is they have really run out of ideas. And when I say ideas I mean ones that could blow the election wide open and still give either a chance of winning an outright majority. When a clip of Alex Salmond joking about writing the Labour budget is your trump card you know you're in trouble.

In six months both have spent millions of pounds to nudge up a couple of points from 32% to 34%. Those gains have basically been made at the expense of UKIP, who have dropped from the heady heights of 18% to around 13-14%.

But the polls are quite interesting in some respects. For example the YouGov offering from April 21/22, which sampled 2060 people, asked, on a scale of 1-10, how likely you are to vote in a general election and 68% said definitely and another 11% gave nine as their answer. That's 79% almost certain to vote. If that was the turnout on May 7th it would be an astonishing jump from what we've been used to in the last 15 years.

Also YouGov make it clear that their 'headline voting intention' poll - the one you get shown in the media - excludes don't knows so the figures outlined are slightly skewed. For example the Conservatives are officially listed as gaining 33% yet they were picked out 577 times out of 2060 (28%).

What that all basically means is there are still a lot of people who are undecided and that is definitely borne out my experience from canvassing in the Leeds North West constituency, where I am standing for the Above and Beyond Party.

Earlier this week I was walking through some of the prettier parts of Headingley, which is a great place to come when the sun is shining. I have been speaking to dozens of people every day and that was a particularly illuminating few hours. At one point I enjoyed a run of eight 'don't knows'.

And you can always tell when they are genuinely undecided. When you stand for parliament what you quickly come to realise is that we British are incredibly polite and those who will listen, but know they are not going to vote for you, just listen and nod their head. Those who are genuinely interested ask questions and it becomes a conversation. They become animated and often frustrated because they can't quite make sense of it all.

I have been campaigning hard for the last three weeks and every day you meet people like that. I know my evidence is only circumstantial but I would say a good 20% of the British public haven't made up their mind, which is also the figure the YouGov poll suggests.

If that's right that is a lot of votes up for grabs and more than enough to make a critical contribution to either of the big two.

I suspect both Labour and Conservative election strategists are focussing their attentions on reaching 300 seats - current projections suggest they will both get around 280 - because that would mean they could form a much more palatable alliance with the Lib Dems, who have made it clear they would be happy to support either.

Attempting to form a four or even five-party coalition would turn into a logistical nightmare for reasons to numerous to list here although it might be fun to follow. Well...for a little while at least. Some stalemates can be quite entertaining and I can't wait to see how it all unfolds post May 7th.
