If Labour keep giving Kemi ammo (and there's no reason to think they won't!), then I do think they'll become more popular.
They're the only party to say they'll bring back the two child benefit cap as well. That will also be popular with voters.
They've recently started showing their policy hand more, which is what was missing. Definitely interesting to watch. To
kind of quote Mark Twain: reports of the Tories' death are greatly exaggerated!
