This is a moderated discussion.  Since we anticipate receiving dozens of comments a minute, we will only be posting a selection – particularly questions that are asked by more than one person participating in the chat. David will answer as many questions he can, but since the chat is only an hour long, he may not be able to get to them all. Apologies in advance. We are saving a copy of all comments and questions.

If you really want your question answered, please resend the question after 10-15 minutes instead of sending in a complaint to the moderator. We can’t post all comments since the tool will be overwhelmed. If you want to share your thoughts on the news and politics (and don’t have questions for David), you can always discuss politics and the news at
