The appointment of the man who was Chancellor at the time of the crash would make it even easier for the Tories to warn "don't give the keys back".
The first poll on the Autumn Statement shows that voters agree with Balls that Osborne is "in denial about the cost of living crisis".
Both Miliband and Balls know they need to do more if people are going to be persuaded to put them in charge of public money.
"We know they’re not very good at shooting badgers...they're not very good at shooting other people’s foxes either."
"Britain simply won’t be able to tackle the cost-of-living crisis that we currently face – or build the strong economy that we need to take us to a more prosperous future – unless we build more homes."
If the Chancellor is willing to offer £12bn of guarantees for mortgage lending, why won't he support New Towns?
Having witnessed the original feud at first hand, both men are conscious of the need to avoid an irrevocable split.
Miliband's adviser Torsten Bell accidentally copied in Conservative MP James Morris, rather than the Labour pollster of the same name.
The key point about the email by a Miliband adviser describing Balls as "a nightmare" is that it was leaked in the first place.
The shadow chancellor charges the Tories with penalising "the ordinary taxpayer" by shifting green charges from bills without punishing the energy companies.
