Letters from a Tory writes "Dear David" letter

One of the leading Conservative blogs, Letters from a Tory, has written a post complaining of the:

• naivety;
• incompetence;
• stupidity; and
• inappropriateness

of the party's current campaigning. It concludes:

I’m not going to lie to you – I will be voting Conservative at the next election, not least because I despise Labour and everything they stand for but also because you deserve a chance to put into practice what you have preached over the last five years. Even so, when my party membership next comes up for renewal, I suspect that my direct debit may well slip by the wayside. Never forget that, while swing voters always need a reason to vote Conservative, party members need a reason to vote Conservative too.

More evidence that there is a surprising degree of hostility towards Cameron and his circle among Conservative rank and file. I wonder if these complaints about strategy mask what is really disagreement with the leadership's strategy of wooing liberal Britain?
