David Cameron has begun to wake up these troubled mornings and notice a series of strange circles on the floor.
They are the rings Ed Miliband has run round him since the Murdoch saga began to intensify and deepen with each revelation.
Cameron contrived to totally misjudge the mood of the nation at a time when it seemed impossible to do such a thing.
So, when Miliband snatched the initiative and tabled a motion in the Commons urging Murdoch to withdraw his takeover bid for BSkyB, the chastened Conservatives had no choice but to scuttle along in his wake.
Rarely has a ramshackle old cart been so proud and delighted to lead a lame horse.
