I think the saddest part of that is that while he's trying to stand up for a group, he's too fearful of making that claim publicly. I don't know if that's him being weak or clever. He wants to stand up for the group Healy identified, I don't doubt that. But he wants to do it without alienating the groups either side, especially the ones higher up for fear of a backlash.
I personally think that Cameron is in No. 10 because the Tories were the only party to put together a coherent philosophy at the last election, and the reason Clegg is there is because Cameron tried to please too many people rather than being bold and brave, alienating some and securing others. It's certainly far too early to judge miliband, or to start backing yourself into a corner by making pledges. Sadly, policy must wait, and wait years. Cameron did the right thing in not committing to policy for years but rather rebranding and all that stuff I hate. While I don't think Miliband should start wearing converse or proclaiming love for the Smith/Killers/popular music group of the week, he should be vague at this point, dealing with philosophy rather than policy detail. At least that's what I think.
