So I'm just going to make a few notes:
-Ignatieff was right when he says Harper's offering "fantasy economics". He also answered the financial question directly. And Harper seemed to make eye contact for the first time. And then went back to the camera. Harper: "Every credible economic analyst" says taxes kill jobs - in Harper's words, that's "simply not true." Ha-Joon Chang & Joseph Stiglitz come to mind, but of course if you exclude those who disagree with you as "non-credible", then you're in a perfectly logically valid circular argument, which is where Harper lives.
