You may be disillusioned, I feel that way sometimes. But being one of the (unfortunate) majority who sits and home and gets radically effected by government policy means you probably regret not getting involved when you realise that to have your say at the ballot box is the only thing that really ensures you exercise your opinion. Even contacting an MP or councillor via email, participating in a 38 degrees campaign or sending a letter, as good as this may appear to many people and as useful as they are as means of contact, does not actually change anything.
Democracy is not perfect. The 'First Past the Post' system renders the majority of seats and therefore the majority of votes pointless in the wider reality of deciding which party wins power. It is known that a handful of votes can change a government either way, perhaps as little as 1000 votes. Crucially, however, these votes have to be in the right seat in order to be the votes that really count. This is unfair on the voter and makes some votes more important than others. It also makes making the case for non-voters to become voters all the more difficult, particularly in non-critical seats.
Activists that I deal with are stoically committed to the power of knocking on doors. I remain unsure and I had a discussion with an "activist's activist" this week who agreed with me that the vote on the day had no real bearing to the many thousands of doors they knocked on during the election and they questioned the ongoing relevance of this means of canvassing. In case you are wondering, this anonymous person is not someone that has appeared on my politics podcast! I accept that breathe a sigh of relief if we are leafleting rather than door knocking, but I do think that people either say they vote for you honestly or pretend to support you just to get rid of you, they say something nasty because it's the only opportunity they have to exercise some bile against politicians or they just don't answer the door. I do believe that being seen out and about does have its benefits, but there is no evidence that the vote collapses in areas where we don't knock, which is many.
I believe that the election result in the May 2015 General Election will increase voter engagement. People will begin to realise that to protest vote, however well-intended, maintains the status quo. As politically opportunistic as this will appear and I make no apologies for it, you will only ever get a Tory or Labour government. Neither are perfect but you choose the overall direction. Do you choose the free market, survival of the fittest of the Conservatives or the enterprising yet socially just focus of Labour. Governments change and Labour will get back in. You decide whether it is 2020 or 2025 when we return. Yes, Labour must offer a presentable and coherent set of ideas, but upon doing so it is you that must vote for it.
