I feel patronised.

I have just been listening to another smug band of studio commentators down in London agreeing that the likes of me couldn't possibly be voting for the Lib Dems for any other reason than because I have been dazzled by the boyish charm of Nick Clegg.

Now, I will admit that I would rather be watching Glee or Over the Rainbow than listening to political point scoring (those shows have something positive to say about the world). But I recognise my civic duty and I have been paying attention.

I have been persuaded to vote Lib Dem because their policies strike me as driven by pragmatism rather than dogma. I am with that questioner who asked the politicians during the final leader's debate: "Why don't you remember that you are here to serve us?" (Rather than your party, I would add).

I don't want to see Britain joining the euro. However, I have been listening hard and I have heard the Lib Dems say again, and again, that they would have us join the euro only if economic conditions were right; and even then only if the Great British electorate could be persuaded to vote to that currency in a referendum. So that's all right then.

I don't think Britain can prosper in glorious isolation from Europe. We can't act like some socially challenged teenager, hanging on the edge of the party trying to be cool. We need friends. To me it is a plus that Nick Clegg can speak a handful of our neighbours' languages, that he is diplomatic and has experience of negotiating Brussels.

On immigration, the Lib Dem amnesty proposal to give illegal immigrants who have been living and working here over ten years, who speak English and have no criminal record, the chance to acquire British citizenship, seems sensible enough to me. I would rather see such people as taxpayers and citizens than outlaws at the prey of criminal gangs. I am against criminal gangs and I do not see why they should be handed such a profitable power-base for their crimes.

On the economy, I took note of that recent report by the Institute for Fiscal Studies that said that, although the declared measures of all the three main parties fell woefully short of what will be needed to repair our country's massive deficits, the Lib Dem's proposals were marginally better than those of either Labour or the Conservatives.

In addition, I am utterly convinced of the need for voting reform. And listening to the Reds and Blues I see no hope of a meaningful reform of the present, startlingly unjust system, without the intervention of the Lib Dems.

Besides, in our constituency, the Lib Dem candidate is the only one who has said that he will fight for the preservation of post offices and defend the Royal Mail from privatisation – and that, I think, is really important.

So I am not voting because of X Factor politics. The television, perhaps, was involved, because for once I had the opportunity to hear extended pitches from the three main parties uncut and without comment, in my own home, where there was enough peace and quiet to think about it. But I have thought and I have paid attention and I don't think my choice deserves to be dismissed and patronised as if I hadn't.
