He was doing so well up to now.

I e-mailed my MP regarding shared residence issues. I asked him if he would consider signing an early day motion at present in Parliament. My e-mail was responded to very quickly and I was pleased by his response to me.

Several weeks later I noticed that he had indeed signed the early day motion.

My MP has a column in the local rag which I now regularly read. I didn't vote for him or his Party, but nevertheless I am impressed with his keen interest in local affairs.

I think the whole thing just show how much Mr C is stuck in a time warp and doesn't actually know whats actually goes on in 'real' life

Surely the question is, why did Cameron decide to write this? Why on Fathers Day? And why in the Telegraph?
(Ok, that's 3 questions)
Cameron isn't stupid and he isn't ignorant. He knows the reality - he's been told often enough, and before the election his party made a series of commitments which would have helped resolve many of the problems we still have to face.
He would have had a team working on that article, polishing it, changing bits here and there, checking that the tone was just right. There will have been nothing spontaneous about it.
So what was it all about?
My answer, for what it's worth, is twofold. One, he is introducing new charges for CSA applications which are going to prove extremely unpopular. He wants the support of the party faithful, the Telegraph readers, so he is flooding them with misinformation so that in their efforts to comply with his request and stigmatise absent fathers they will gloss over this particular little injustice.
Two, he has abandoned every one of the commitments made pre-Election (because Clegg forced him to) and, again, he doesn't want to lose his voters, so he is trying to blame fathers for his cowardice and for the failure of his policies (and they will fail).
Thirdly (sorry, that's 3 reasons) he's seen Obama do the same thing every Fathers Day and he wants to be like his hero.
