Here are the most pertinent quotes:
“Genuinely I feel that being a mum means you have a real stake in the future of our country, a tangible stake.”
[May] “possibly has nieces, nephews, lots of people. But I have children who are going to have children who will directly be part of what happens next”.
Anyone who can't see that as her saying it gives her an edge would seem to be willfully narrow in their reading of Leadsom's words.
Still, she'll make enough noise in the hope that Tory Party members will close their eyes and their minds and assume it's a smear from the left-wing Times. Which is how I see her campaign going, dog-whistling and faux-innocence, and then claiming victim status. Her next go using this tactic will be more subtle.
