Not so useless after all?

Just another quicky, but doesn't this breaking story, about Blair and Brown coming out to launch a massive public scaremongering session, suggest they might have been just a little bit rattled by the reaction they've picked up to the Tory plans?

Forgive me if I'm barking up the wrong tree - I do tend to get overly optimistic come election time - but having appeared to have barely spoken to each other for weeks this does seem to be an interesting shift and makes me wonder what caused it.
