Why is the Liberal Party So Eager to Self Destruct?

Who would think that circulating something like this would convince Canadians that the Liberals are a serious party? Seems almost every day, we have another example of catty, adolescent backstabbing akin to the conversational style of junior high school girls hanging out in the washroom at recess.  Oh well, who am I to complain?  If they want to turn off more Canadians, that's just fine with me.
