It's quite revealing how you can edit or manage the process and output to create a set of impressions. If you subjected tonight's process to an expert review, I think it would show bias.
Cameron looks at ease but isn't getting it all his own way. "I haven't made a forecast" (about how much immigration will fall due to his alleged reforms).
I have a strong suspicion that ignoring concerns about immigration (Labour and Conservative) will lead to Brexit, this time or next.
You've got to watch these things. Just occasionally,there is a glimmer revealed of what somebody really thinks or feels. Somebody's nose growing exponentially, or involuntarily following through after a particularly tough question.
We can live in hope.
