Stephen Harper's Conservative Party is Rosemary's Baby.  There are no progressives in it.  Harper made sure of that when he sent MacKay to stab Orchard in the back and alienated the few remaining red Tories who had any integrity. 

The few current leadership candidates who aren't peddling hard right social policy are full blown Randian libertarians of the Paul Rand variety.  Kooks who would sell every public asset (for short term gain) and erode revenue to the point where privatizing every public service would be the only thing left (yeah, thanks but no thanks).  

And the remainder (Kellie Leitch, Blaney) combine the above "feature" with punitive social policies that demonize anyone who isn't white and socially conservative.
