"The official said there was not a single reason that explained the “red-lighting” of Mr. DeSousa’s candidacy.  Instead, the Liberal Party and Mr. Trudeau made a subjective assessment in relation to Mr. DeSousa and whether he was the right person to become the face of the party in St-Laurent, the official said."

Lets see what could that top secret "subjective" reason possibly be?   

Could it be that DeSousa lives in the riding? ... is male? ... middle aged? ... not the "right" visible minority? ... is not a lap dog and speaks his mind? ... can think for himself? ... is smarter? more qualified? has more life experience? and more accomplished than Justin?  

or is it because of his small stature? ... wears glasses? ... drives a Honda? ... has two children? ... is a bird lover ... shovels his own driveway? ... doesn't vacation with the Aga Khan? ... keeps his promises? ... doesn't sell out fellow Canadians? ... treats people with respect and dignity? ...
