If you don't know who Dean Del Mastro is, you should - he's the perfect example of why Stephen Harper keeps the iron fist he does on the Conservative caucus.
First off, let's start with the most recent infraction - questioning the faith of Papineau Liberal MP Justin Trudeau, all because a local Catholic school in Del Mastro's Peterborough riding invited Trudeau to speak to students about youth and leadership. Not on any theological issue, but on leadership, something Del Mastro has no clue about, to be sure. And yes, I encourage everyone to go on Dean's "fan page" on Facebook and let him know just how much you appreciate those comments, as well as the continued attack by Del Mastro on various things involving Trudeau, because hey, he's just that bitter, for some odd reason.
Then we move to Dean's involvement on the attacks on the CBC, which Impolitical goes into so much better detail than I can.
Don't forget Del Mastro's wonderful decision to commission a poll because he didn't like another poll that showed his PC cousin behind in the provincial Peterborough riding this past September
There's a long line of things that apparently get Dean all in a huff, from apparently being called fat (get over it, Dean), to calling Jack Layton and the entire NDP caucus traitors, to saying the anti-proroguers were a media tool, and on it goes in this helpful collection of Dean-related articles in Maclean's.
I'm not sure how this one slipped past those super careful nutbar warning systems the Conservatives have, but I do know that the people of Peterborough deserve better representation that this guy.
