Gina Miller is simply amazing. She has a clear, rational commitment to an ideal, which is impressive enough for a start - and increasingly rare. She's got courage and consistency, and is prepared to back them with her own money. But what's astonishing is the fortitude with which she faces the tide of abuse which greets her efforts. If you wanted a strong argument against Brexit you might well pick the way in which it's lowered the tone of public debate. She has every reason in the world to give up, get angry, be abusive back, but no. It's not about her, it's about the principle, so that's what she concentrates on, regardless of what's thrown at her. Like I say, I'm amazed. But also grateful. We could do with more like her, and soon.
