As well as David Cameron's principle problem of making everyone feel the benefits of an economic recovery, there is also the issue of Ed Miliband quite successfully pitching himself as a kind of insurgent figure.
First against Murdoch, then against the energy companies; today against the Daily Mail.
You may have your own views against those individual issues, but he is beginning to ride the winds in opposition with a degree of success that he didn't manage a year ago.
I think both of those things bother David Cameron and needs to address them over the next 18 months.
