Why is it that the Conservative campaign is rife with overzealous control freaks screening potential participants and declaring them unfit to gaze upon Dear Leader? I’ll tell you why: Because Harperites become hysterical when they are told that they are mistaken about anything. There’s no better way to prevent fits of hysteria than preventing other points of view from even being aired. That’s why curious students are intimidated in Guelph. That’s why advocates for homeless veterans are refused in Halifax. That’s why even the friendliest media members are limited to five questions a day. The politburo cannot be wrong.
