Speaking of sucking up oxygen, I see five articles headlining O'Leary on the Globe's home page right at this moment.  Based on a search I see Michael Chong has been mentioned in a story title this many times in the last three months: once.  Yet, Mr. Chong has incisive and relevant things to say about the carbon tax and structure of income tax, immigration, small business, affordable housing, greenhouse gas emissions, employment and the economy.   O'Leary is a blowhard which makes for a very easy story.  It's lazy journalism though and deprives the country of the kind of oxygen that it really needs.  When are we going to start talking about genuine issues again.  (I am not involved with the Chong campaign, but like what he has to say.)
