Actually it is, at least in part, the Bloc Quebecois' fall as well.

This is right smack in the middle of the Bloc Quebecois heartland.  Rural Quebec a little ways from Quebec city.  This has been a strong separatist area for ages. Case in point, in the 1995 referendum the Lac-Saint-Jean Quebec Provincial riding (similar though not identical to the current Federal riding) voted 73% in favour of separating, the highest level in the entire Province.

Without a sitting cabinet minister this is a riding the Bloc would normally hope to win.  Of course maybe some people in the riding are hoping Richard Hébert will become a cabinet minister.
