If this is a recovery, the voters will ask, why aren't we feeling it? Cameron and Osborne need to offer answers.
If they are to remain the largest party after 2015, the Conservatives need the Lib Dems to win back left-leaning voters in Tory-Labour marginals.
The Deputy PM vowed in his conference speech that the Lib Dems "will keep this government green" - and he meant it.
The balance of credit for getting the Tories even this far has clearly tilted towards the Chancellor.
The cap is less a serious act of policy than a political weapon designed to trap Labour on the wrong side of the argument and to demonise the unemployed.
