Let me start by offering my congratulations. I was rooting for you, I voted for your candidate (even in Oxford East, that little bastion of red in the midst of deep blue rural England), and I'm pleasantly surprised by the result. I think that given the available options, and the current circumstances, you and your party were the least bad option. And if that sounds a bit like damning with faint praise, Mr Cameron, well, so be it.
Here's the thing. Most of the people I know and respect - not all, but most - think that voting Conservative makes you some sort of amoral monster. I'm not exaggerating, or at least not much. And can I be honest, you haven't helped us. You ran a campaign based on fear; you won an election at least partly by making us afraid of one another. I know the other guys were doing just the same thing, and I know it's easier to sell your opponents' nightmare than your own dream; but I'm sure some of the bitterness I'm seeing springs from that campaign.
Listen, Mr Cameron (I know you prefer 'Dave', but I can't quite bring myself to first-name a sitting Prime Minister): I really believe that a smaller state and a bigger civil society can be the best way forward for society; I think you believe it too, but you didn't exactly sell it, that's all.
But actually that's not the main thing. It's not nice to be considered an amoral monster, but I can hold my own and I'm prepared to make a positive case even if you're not. The main thing is that I need you to prove them wrong, and that's going to need a change in approach from you. I believe you when you say that you want to protect the most vulnerable, but people I know are not seeing that desire translate into action. They don't believe you, because your record and rhetoric don't line up. Mr Cameron, in your second term, will you ensure that necessary cuts don't punish those who are already suffering? Will you take a personal interest across government in protecting those who cannot protect themselves?
Like you, I think it is important that we don't take the approach of many on the left, which seems to be to classify large numbers of people as 'poor' and assume they will always be dependent on the state; but on the other hand, there are people who will always be dependent, because they are chronically ill, or disabled. For them, especially, you need to do better than you have so far. Compassionate conservatism - that's what I want to see.
Mr Cameron, there's a lot more I could say, but frankly if you take this one thing on board I will be happy. As a Christian, I am commanded to respect you and to pray for you as a leader. I'll be doing those things going forward, and God bless you as you make difficult decisions.
