The other part to Cameron's speech was a warning about a hung parliament. Or as he put it: "If we get any other result, then we could be stuck with the problems we've got now." I lost count of how many times he used the word "decisive" as part of this. "We need decisive leadership ... decisive government ... only a decisive Conservative win," etc. You can see why he's making this point, and there's a good slug of truth to it. But, again, the question is whether people will listen. Or will they just see it as the self- interest of a traditional politician.
So, some answers from the Tories today - but two questions over which, really, they have only a marginal degree of control. Public, it's over to you.
