I can't imagine that will go over well in the CPC's Quebec/New Brunswick constituencies. Doesn't strike me as a winning strategy (though when you're not bilingual, maybe you don't have any good options).
No idea what the top if the party is thinking seeeing O'Leary at the top and can't speak French unless he's phonetically reading what he wants to say off a sheet of paper. Like they need to know it's an impossibility to get him elected across all of Canada since he can't speak French.
