Chong is showing that he is principled by supporting a carbon tax and by saying that it is time to study anti-Muslim sentiment.  He proved it before by resigning from Harper's cabinet over Quebec.  Probably the best of a bad lot.

But I don't see how he can make the claim that a revenue neutral scheme (eg balancing the carbon levy with cuts to income tax) will stimulate the economy.  Cash out of pocket is cash out of pocket no matter where it ends up.  Sure, the carbon tax could be redirected toward green schemes to bolster innovation....but that could just as easily be done with the income tax he will be forgoing.
